摘要
聚芳醚酮由于熔融粘度大和加工温度高而影响了其进一步工业化,因此降低熔融粘度和加工温度是研究聚芳醚酮的新课题[1].目前在工程塑料中热致液晶高分子是一种具有低熔融粘度而性能优异的材料,其熔融粘度比一般高分子材料低得多,并且具有优异的机械性能[2]本文采用无现...
The synthesis and characterizatiqn of a novel thermotropic liquid crystalline poly (aryl ether ketone)-DBCl based on the reaction of a liquid crystalline mesogenic monomer biphenol and a crystal-disrupting monomer 2-chlorohydroquinone with 4, 4' -difluorobenzophenone are investigated. The novel poly(aryl ether ketone) maintains the excellent properties of the common poly(aryl ether ketone)s and shows a typical nematic texture.
