    Notes: Abstract A dicarboxylic acid (1,7-BTMPN) bearing two preformed imide rings, was prepared from the condensation of 1,7-bis(4-aminophenoxy)naphthalene and trimellitic anhydride. A new family of poly(amide-imide)s with inherent viscosities up to 1.56 dL/g (0.5g/dL in DMAc at 30 °C) was prepared by the triphenyl phosphite activated polycondensation from the diimide-diacid 1,7-BTMPN with various aromatic diamines in a medium consisting ofN-methyl-2-pyrrolidone (NMP), pyridine, and calcium chloride. Most of the resulting polymers were readily soluble in polar solvents such as NMP and DMAc. All the soluble poly(amide-imide)s can form transparent, flexible, and tough films. The glass transition temperatures of these polymers were in the range of 185–267°C and the 10% weight loss temperatures were above 430 °C in nitrogen.

    Notes: A dicarboxylic acid (1) bearing two phthalimide rings was prepared by the condensation of N-phenyl-3,3-bis[4-(4-aminophenoxy)phenyl]phthalimidine and trimellitic anhydride. A new family of poly(amide-imide)s having inherent viscosities of 0.65-1.65 dl/g was prepared by the triphenyl phosphite activated polycondensation of the diimide-diacid 1 with various aromatic diamines in a medium consisting of N-methyl-2-pyrrolidone (NMP), pyridine, and calcium chloride. All the resulting polymers showed an amorphous nature and were readily soluble in polar solvents such as NMP and N,N-dimethylacetamide. The soluble poly(amide-imide)s afforded transparent, flexible, and tough films. The glass transition temperatures of these polymers were in the range 249-340°C and the 10% weight loss temperatures were above 545°C in nitrogen.

    Notes: Fifteen bis(trimellitimide)s 2a-o were prepared by condensation of the corresponding aliphatic or aromatic diamines with trimellitic anhydride. A series of structurally new poly(amideimide)s were synthesized by the direct polycondensation of these bis(strimellitimide)s with 2,5-bis(4-aminophenyl)-3,4-diphenylthiophene using triphenyl phosphite and pyridine as condensing agents in N-methyl-2-pyrrolidone (NMP). The resultant poly(amide-imide)s have inherent viscosities in the range between 0,72 and 2,73 dL/g at 30°C in N,N-dimethylacetamide (cf. Tab. 2). The polymers are amorphous and readily soluble in polar aprotic solvents such as N,N-dimethylacetamide (DMAc) and NMP. Transparent and tough films can be cast from their solutions. Most aliphatic-aromatic poly(amide-imide)s show a glass transition in the range between 203 and 242°C in their differential scanning calorimetry (DSC) traces, whereas the wholly aromatic poly(amide-imide)s show no discernible transition before decomposition. The thermal stability of the polymers was evaluated by thermogravimetry which showed the 10% weight-loss temperatures in the range between 414 and 459°C in air and between 451 and 578°C in a nitrogen atmosphere for the aliphatic-aromatic poly(amide-imide)s and above 500°C in both air and nitrogen atmosphere for the wholly aromatic poly(amide-imide)s.

    Notes: A series of novel bis(phenoxy)phthalimidine-containing poly(amide-imide)s III were synthesized by the direct polycondensation of 3,3-bis[4-(4-aminophenoxy)phenyl]phthalimidine (BAPP) with various aromatic bis(trimellitimide)s in N-methyl-2-pyrrolidone (NMP) using triphenyl phosphite and pyridine as condensing agents. Poly(amide-imide)s III, having inherent viscosities up to 1.36 dL/g, were obtained in quantitative yields. All resulting polymers showed an amorphous nature and were readily soluble in polar solvents such as NMP and N,N-dimethylacetamide. All the soluble poly(amide-imide)s afforded transparent, flexible, and tough films. The glass transition temperatures of these polymers were in the range of 267-322°C and the 10% weight loss temperatures were above 490°C in nitrogen. Some properties of poly(amide-imide)s III were compared with those of the corresponding isomeric poly(amide-imide)s III′ prepared from 3,3-[4-(4-trimellitimidophenoxy)phenyl]-phthalimidine and various aromatic diamines. © 1996 John Wiley & Sons, Inc.

    Notes: Various dicarboxylic acids with preformed imide rings were readily obtained by the condensation of ω-amino acids and aminobenzoic acids with trimellitic anhydride, and omega;-amino acids with pyromellitic dianhydride. New tetraphenylthiophene-containing poly(amide-imide)s having inherent viscosities of 0.58-1.54 dL/g were prepared by the direct polycondensation reaction of 2,5-bis(4-aminophenyl)-3,4-diphenylthiophene with the imide-containing dicarboxylic acids using triphenyl phosphite and pyridine as condensing agents. These polymers were amorphous and readily soluble in a variety of solvents such as dimethylacetamide (DMAc), dimethylformamide (DMF), and N-methyl-2-pyrrolidone (NMP), and could be easily solution cast into transparent, flexible, and tough films. Most of the poly(amide-imide)s showed clear glass transition on the heating traces of differential scanning calorimetry (DSC) in the range of 146-244°C. Almost all the poly(amide-imide)s exhibited no appreciable decomposition below 400°C, with 10% weight loss being recorded above 420°C in nitrogen. © 1992 John Wiley & Sons, Inc.

    Notes: Seven imide-containing dicarboxylic acids IIa-g were synthesized from pyromellitic dianhydride and amino acids of the formula HOOC - (CH2)m - NH2, with m - 1,2,3,4,5,10,11. These diacids were condensed directly with 3,3′- or 4,4′-sulfonyldianiline using triphenyl phosphite in N-methyl-2-pyrrolidone (NMP)-pyridine solution containing calcium chloride and lithium chloride. The resulting poly(amide-imide)s have moderate to high inherent viscosities ranging from 0.47 to 2.02 dL/g in dimethylacetamide. These polymers showed excellent solubility in polar solvents such as NMP, and most of them could be cast into transparent and tough films. Glass transition temperatures (Tgs) of these poly(amide-imide)s were recorded in the range 116-258°C and increased with decreasing number of methylene groups in the repeated unit. The polymers with longer aliphatic chains (e.g., m = 10 and 11) exhibited higher crystallinity, higher initial decomposition temperature, and lower solubility in polar solvents.

    Notes: 3,3-Bis[4-(4-aminophenoxy)phenyl]phthalide (II) was used as a monomer with various aromatic dicarboxylic acids and dianhydrides to synthesize polyamides and polyimides, respectively. The diamine II was derived by a nucleophilic substitution of phenolphthalein with p-chloronitrobenzene in the presence of K2CO3. Polyamides IVa-g having inherent viscosities of 0.77-2.46 dL/g were prepared by the direct polycondensation of diamine II with diacids IIIa-g using triphenyl phosphite and pyridine as condensing agents. The polyamides were readily soluble in a variety of solvents such as N, N-dimethylformamide (DMF), N,N-dimethylacetamide (DMAc), and N-methyl-2-pyrrolidinone (NMP) and afforded transparent and flexible films from the polymer solutions. These polymers had glass transition temperatures (Tgs) in the 227-307°C range and 10% weight loss temperatures occurred up to 450°C. Polyimides VIa-e based on diamine II and various aromatic dianhydrides Va-e were synthesized by the two-stage procedure that included ring-opening, followed by thermal or chemical conversion to polyimides. Most of the polyimides obtained by chemical cyclodehydration procedure were found to soluble in DMF, NMP, o-chlorophenol, and m-cresol. The Tgs of these polyimides were in the 260-328°C range and showed almost no weight loss up to 500°C under air and nitrogen atmosphere. © 1994 John Wiley & Sons, Inc.

    Notes: The novel diamine, 1,7-bis(4-aminophenoxy)naphthalene (1,7-BAPON), was synthesized and used to prepared polyimides. 1,7-BAPON was synthesized through the nucleophilic displacement of 1,7-dihydroxynaphthalene with p-fluoronitrobenzene in the presence of K2CO3 followed by catalytic-reduction. Polyimides were prepared from 1,7-BAPON and various aromatic tetracarboxylic dianhydrides by the usual two-step procedure that included ring-opening polyaddition to give poly(amic acid)s, followed by cyclodehydration to polyimides. The poly(amic acid)s had inherent viscosities of 0.74-2.48 dL/g. Most of the polyimides formed tough, creasible films. These polyimides had glass transition temperatures between 247-278°C and their 10% weight loss temperatures were recorded in the range of 515-575°C in nitrogen atmosphere. © 1995 John Wiley & Sons, Inc.
