甲基丙烯酸甲酯与N-苯基甲基丙烯酰胺本体共聚合的研究
BULK COPOLYMERS OF METHYL METHACRYLATE AND N-PHENYL METHACRYLAMIDE
【摘要】 <正> 改进聚甲基丙烯酸甲酯(简称PMMA)耐热性能的方法,有采用将甲基丙烯酸甲酯(简称MMA)与多官能团的单体如甲基丙烯酸丙烯酯、甲基丙烯酸酐等共聚制得具有部分交联的共聚物;也有采用MMA与带有极性基团的单体如甲基丙烯酸、甲基丙烯酰胺(简称MAD)等共聚制得线型共聚物,以及其他方法。我们实验室曾报道了MMA
【Abstract】 It hs been found that the title copolymers are more heat-resistant than polymethyl methacrylate. When the amount of the amide changes from 5 to 10% the softening points of the copolymers increase from 140 to 154℃, presumably due to the increase in hydrogen bonds through the introduction of amide groups.In comparison with MAD-MMA copolymers, the φA-MMA copolymers have better water-resistance.
