Synthesis and oxirane ring-opening polymerization of tetrahydrophthalimide glycidyl derivatives

Abstract Tetrahydrophthalimide glycidyl derivatives have been synthesized and then polymerized using Al (OiPr) 3 /ZnCl 2 (1:1) as catalyst. Depending on which heteroatom was directly attached to the glycidyl moeity, different results were obtained. When it is linked to imidic nitrogen, longer reaction times were required but higher molecular weights were obtained, as deduced from the non-detection of end-groups by elemental analysis and 1 H-NMR spectra. By means of 1 H- and 13 C-NMR spectra, the oligomeric structure has been characterized. Two fractions, isotactic and atactic, could be isolated. Thermal behaviour has been studied by DSC and TGA.

Preparation and thermal behaviour of copolymers from glycidylether and glycidylimide

Abstract Copolyethers with nadimide or tetrahydrophthalimide derivative pendant groups were prepared by ring-opening polymerization from phenylglycidylether and the corresponding glycidylimide. Elemental analyses led to the compositions of the copolymers which do not closely coincide with the ratio of monomers in the feed. The thermal behaviour of the copolymers was examined and properties of copolymers were compared with these of the homopolymers.
