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。
