✦ Synopsis

Homoand copolyimides with high molecular weight could be synthesized from three dianhydrides and three diamines following two different one-step methods. Solubility behavior with structural effect, viscosity, kinetics of solution imidization, synthesized method, mechanical and thermal properties, and effect of azeotroping agent are discussed. Results indicate that homo-and random copolyimides were only prepared from a one-step method; on the other hand, copolyimide with different arrangement, such as random, block, and alternating, could be synthesized by a modified one.

## Abstract A thermoplastic poly(glycerol sebacate) elastomer (TMPGS), prepared by a two‐step method for the first time, is characterized in the present work. First, non‐crosslinked poly(glycerol sebacate) (PGS) prepolymers at the 1 : 1 molar ratio of glycerol to sebacic acid were synthesized throu
