✦ Synopsis
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 eopolymers was examined and properties of copolymers were compared with these of the homopolymers.
