一种含三氟甲基侧基的聚酰胺酰亚胺的<br /> 合成与性能研究<br />
Journal Title: Science Paper Online - Year 2007, Vol 2, Issue 8
Abstract
本文采用分子设计的方法，合成一种新型含三氟甲基侧基的二氨单体。并运用一步合成法，得到高分子量可溶性聚酰胺酰亚胺。通过1HNMR、FT-IR、TGA 、DSC等对所制备聚合物的结构和性能进行了表征。结果表明，合成的聚合物为无规高分子结构，易溶于N-甲基吡咯烷酮，N，N-二甲基乙酰胺和四氢呋喃等极性溶剂中；其10%的分解温度为524.0℃，玻璃转化温度（Tg）为214℃；断裂伸长率为10.5%，强度为131.6MPa，模量为2463.0 MPa。
