摘要
聚酰亚胺以其优异的热性能而引起人们广泛关注,40多年后的今天它仍然是在高耐热塑料中保持领先地位的一种优异的高分子材料。本文从二酐与二胺两步法及一步法合成聚酰亚胺展开论述。
Polyimide caused widespread concern with its excellent thermal performance,40 years later it is still in an excellent position in the high heat-resistant plastic.Tn this paper,The dianhydride and diamine is as raw materials ?One step and two-step synthesis of polyimides is applied.
