    Notes: Treatment of 2,7,8-trioxabicyclo [3.2.1] octane (I) with electrophilic initiators gave polyorthoester composed of five- (70-86%), six-, and seven- (the sum, 14-30%) membered rings. Treatment of 2,8,9-trioxabicyclo [3.3.1]nonane (VI) with electrophilic initiators gave mainly oligomers. Trifluoromethane sulfonic acid in dichloromethane was particularly effective for the formation of dimer, 2,8,10,16,17,18-hexaoxatricyclo[11.3.1.1]hexadecane. The analysis of the structures of poly-I and oligomer-VI suggests that I and VI are polymerized through an SN1 mechanism.

    Notes: The behavior of the readily available cis- (1) and trans- (2) 4, 5-epoxy-2-pentenals toward classical cationic, anionic, and free radical initiators has been examined. Only the cationic polymerization of 1 gave soluble polymer of moderate molecular weights. This polymer possessed predominantly the cyclopolymerized furanose structure 12. Cationic initiation of 2 and anionic initiation of both 1 and 2 gave only crosslinked materials, and free radical initiators with 1 and 2 gave no polymer.

    Notes: Phosphorus-containing polyamides and polyesters, which had tricyclic fused rings (phenothia-phosphine rings) in the main chain, were prepared and the properties of the resulting polymers were examined. These polymers were obtained at highly reduced viscosities in satisfactory yields by the polycondensation of 2,8-dichloroformyl-10-phenylphenothiaphosphine 5,5,10-trioxide with aromatic diamines or bisphenols. The polyamides and polyesters were soluble in polar aprotic solvents such as dimethylacetamide and N-methyl-2-pyrrolidone; the polyesters were also soluble in chloroform. The polymers exhibited good heat resistance. The phenothiaphosphine-containing polyamides and polyesters self-extinguished immediately when flame was removed and were highly flame-resistant. The polyester obtained from bisphenol A showed a limiting oxygen index value of 43.5.

    Preparation of phosphorus-containing polymers. XXV. Polyamide-imides that contain phenoxaphosphine rings (1981)

    Notes: New phenoxaphosphine-containing polyamide-imides were prepared by cyclodehydration of the polyamide-amic acids obtained from 8-chloroformyl-10-phenylphenoxaphosphine-2,3-dicarboxylic anhydride 10-oxide and diamines by a low-temperature solution polycondensation. Polymers with reduced viscosities of 0.10-0.59 dl/g in DMA or concentrated H2SO4 at 30°C were obtained in 64-97% yields. All the polyamide-imides were soluble in m-cresol, concentrated H2SO4, and dichloroacetic acid and some of them were soluble in DMF, DMA, and DMSO; the polyamide-imides had better solubility in organic solvents than phenoxaphosphine-containing polyimides. The phenoxaphosphine-containing polyamide-imides derived from aromatic diamines exhibited excellent thermal properties and little degradation below about 400°C, whereas the polymers from aliphatic diamines began to lose weight at about 250°C. They appeared to have thermal stability between phenoxaphosphine-containing polyimides and polyamides. These polyamide-imides exhibited self-extinguishing behavior.

    PhenazasilineThe nomenclature of tricyclic heterocycles described in this paper is according to Chemical Abstracts.-containing polyamides and polyesters (1983)

    Notes: A Phenazasiline ring was incorporated into a polymer backbone by polycondensation of 2,8-dichloroformyl-5,10-dihydro-5-methyl-10,10-diphenylphenazasiline (V) with aromatic diamines or bisphenols, and phenazasiline-containing polyamides and polyesters were obtained. The polyamides were prepared by low-temperature solution polycondensation in N-methyl-2-pyrrolidone (NMP) in the presence of lithium chloride. The polyesters were synthesized by interfacial polycondensation in a mixture of 1,2-dichloroethane and aqueous alkali in the presence of tetrabutylammonium chloride as an accelerator. These reaction conditions gave the corresponding polymers with high viscosities. The phenazasiline-containing polyamides exhibited good solubilities in polar aprotic solvents such as dimethylformamide, dimethylacetamide, and NMP, and also in m-cresol, although the polyesters showed limited solubilities in organic solvents. Under nitrogen, the phenazasiline-containing polyamides and polyesters showed little degradation below 400°C and had good heat resistance.

    Properties of isocyanurate-type crosslinked polyurethanes (1973)

    Notes: Polyurethane elastomers containing isocyanurate rings as crosslinking structure were prepared by crosslinking the prepolymers in N,N-dimethylformamide solution with sodium cyanide catalyst. Physical properties such as gel fraction, swelling ratio, density, glass transition temperature, Young's modulus, tensile strength, and elongation at break were measured. The effects of diisocyanate structure, the degree of crosslinking, and the crosslinking structure on the properties of polyurethanes were studied. The stress-strain curves of isocyanurate-type crosslinked polyurethanes prepared from poly(oxytetramethylene)glycol rose at lower extensions and gave higher tensile properties than those of triol-cured and diamine-cured polyurethanes. The observed high tensile properties were attributed to the rigid crosslinking structure of isocyanurate ring.

    Notes: New phenoxaphosphine-containing polyester-imides were prepared by the interfacial polycondensation of a dichloroformyl-phenoxaphosphine derivative containing a preformed imide ring with five bisphenols. The polymerizations, which were carried out in a chloroform-aqueous sodium hydroxide mixture, afforded polyester-imides with reduced viscosities of 0.60-1.55 dL/g in 61-95% yields. The preformed imide ring did not undergo hydrolysis under the polymerization conditions. Several of the polymers were soluble in chloroform and could be cast into flexible and transparent films. The phenoxaphosphine-containing polyester-imides have good thermal properties, exhibiting little decomposition below 400°C. They appear to be more thermally stable than phenoxaphosphine-containing polyesters, but are not as thermally stable as the corresponding polyimides and polyamide-imides. The order of thermal stability for phenoxaphosphine-containing polymers in air is polyimide ≳ polybenzoxazole 〉 polyamide-imide ≳ polybenzimidazole 〉 polyester-imide 〉 poly-1,3,4-oxadiazole ≳ polyamide 〉 polyester. The polyester-imides exhibited self-extinguishing behavior.
