Notizen: A one-pot synthesis of [5 + 6]-, [6 + 6]-, and [6 + 7]-rigid bicyclic guanidines (6, 8, 19, 21, 23) based on a bis(iminophosphorane)-mediated annulation strategy is reported. The crystal and molecular structure of the parent [5 + 6]-bicyclic guanidine 8 has been established by X-ray diffraction. The crystallographically independent molecule forms dimers through a centre of symmetry by N-H-N hydrogen bonds. The molecule, and therefore the dimer, is statistically disordered in a 65/35 ratio. A statistical study of N-H-N hydrogen bonds of this kind of dimers has been carried out by using the Cambridge Structural Database.

Beschreibung / Inhaltsverzeichnis: Äthylen-Propylen Copolymere, die mit spezifisch syndiotaktischen Katalysatoren dargestellt werden, enthalten sowohl Kopf-Schwanz als auch Schwanz-Kopf orientierte Propyleneinheiten. Daher ist diese Copolymerisation eigentlich eine Terpolymerisation und die einfache Propylenpolymerisation eine binäre Copolymerisation.Die sich daraus für die Kinetik der Polymerisation und Copolymerisation ergebenden Konsequenzen werden untersucht.

Notizen: Ethylene-propylene copolymers prepared with syndiotactic specific catalysts contain both head-to-tail and tail-to-head oriented propylene units. Consequently, this copolymerization is, actually, a terpolymerization, and the propylene polymerization is a binary copolymerization.The consequences of this fact on the kinetics of polymerization and copolymerization are considered.

Notizen: In order to elucidate the relations between morphological habits, thermal behaviour and chemical structure of polymers, aliphatic polyesters with variable amount of trans-double bonds along the backbone chain were crystallized from dilute solutions in 1-propanol and 1-butanol. The crystals were studied with electron microscopy, differential scanning calorimetry, and wide angle X-ray diffraction. The morphology of solution grown single crystals and some thermodynamic quantities such as the equilibrium dissolution and melting temperature and the enthalpy and entropy of fusion are influenced by the percentage of unsaturated comonomer. The thermal behaviour and the X-ray diffraction of these crystals suggest that saturated and unsaturated repeating units are able to cocrystallize.

Notizen: In the present paper we have investigated the role that the presence of trans double bonds plays on the glass transition temperature of linear polyesters. Experimental data indicate that the glass transition temperature is increased by an increase of the unsaturation concentration. The effect is not drastic but it is well detectable. This result is discussed taking into account the chain microstructure and the bulk structure effects.

Notizen: Copolyesters derived from adipic acid, trans-3-hexenedioic acid and 1,16-hexadecanediol were prepared and investigated by means of X-ray diffraction and DSC techniques. From the X-ray results an isomorphous replacement of the saturated and unsaturated diacid units has been suggested. The equilibrium melting temperature Tm0 and the heat of fusion ΔHf were slightly dependent on the copolyester composition. The crystallization process was analyzed by means of Hoffman's kinetic crystallization theory for a lamellar type crystal growth. The values of the free energy of formation of a nucleus of critical dimensions φ* and the free energy of folding σe were found to decrease regularly with increasing amount of double bonds, varying from 110 to 83 kJ/mol for Δφ* and from 171 to 127 erg/cm2 for σe. This effect has been interpreted on the basis of an increase of chain flexibility owing to the presence of the trans double bonds.

Notizen: The dynamic mechanical behaviour of polyamide systems containing different degrees of unsaturation was analyzed. The results do not show any simple relation between unsaturation and mechanical response. Particular attention was given to the α-transition, that is a glass transition, and experimental data suggest that the generally accepted mechanism for this transition requires a more extensive study.

Notizen: Base functionalization of saturated ethylene-propylene rubbers (EPR) was performed either by means of the radical grafting of 2-(dimethylamino)ethyl methacrylate onto EPR or by the reaction of a succinic anhydride grafted EPR with N,N-dimethylethylenediamine. Differences in the structure of the grafted molecules and in their thermal stability are also reported. An investigation is made on the reactivity of EPR having tertiary amino pendant groups toward acid functionalized EPR leading to gelation.

Notizen: The dynamic mechanical relaxations of poly(ethylene terephthalate) (PET), poly(1,4-cyclo-hexylenedimethylene terephthalate) (PCHDMT), and a copolymer of them (COP) were measured in the temperature range from -150 to 150°C by use of a dynamic viscoelastometer. The viscoelastic relaxations of COP are studied and compared with those of PET and PCHDMT. The anisotropy of the viscoelastic properties of stretched COP samples was also studied in order to distinguish between main and secondary relaxations.
