摘要
溶液法合成了一些低分子量的羟端基低聚苯醚砜,并由相转移催化剂将之转为热反应大分子单体——α,ω-双甲基丙烯酸聚苯醚砜酯;用FTIR、~1H-NMR对其结构进行了表征,GPC、VPO对其分子量进行了分析和测定;用DSC、DTA对聚苯醚砜双烯大分子单体的转变温度、热反应过程进行了测定和分析。
Series of hydroxy-terminated poly(ether-sulfone)s oligomer with different molecular weights were synthesized in solvent, then were transformed into a,w-bis (methacrylate)poly (ether-sulone)s macromer by phase transfer catalyst. Their structure and functionility was characterized with FTIR spectrum, 1H-NMR spectroscopy. Their molecular weight was determined with VPO and GPC. Thermalanalysis of this macromer demonstrates its thermal reactivity.
