摘要
以己二醇二醇、亚甲基二异氰酸酯、多核二酐和二胺为原料合成了co - p - p -氨基亚胺(CPUI)。对CPUI薄膜和塑件进行了加工，并对其力学性能进行了评价。在使用相同的启动cpu时，指出了聚合物溶液形成的薄膜和熔融聚合物形成的模塑的规格差异。薄膜和模塑具有弹性体的典型性能。通过使用注射成型方法对所研究的共聚物进行再加工，可以将cpu分配给热塑性弹性体或所谓的热弹性体。
The Co-Poly(Urethane-Imide) Heat Resistant Thermoplastic Elastomers
Co-Pоly (Urethane-Imide) s (CPUI) based on pоly (diethyleneglycol) adipate diol, tolylenediisocyanate, multinucleate dianhydrides and diamines were synthesized. The films and moldings from CPUI were processed and their mechanical characteristics were evaluated. Distinctions of specifications of the films formed from polymer solutions and the moldings formed from melt polymers are indicated when using the same starting CPUI. It appears that films and moldings possess typical properties of elastomers. The reprocessing of studied copolymers by using the injection molding method allows to assign CPUI to the thermoplastic elastomers or so-called thermoelastoplasts.
