含乳酸酯链节的不饱和聚酯(续)
AN UNSATURATED POLYESTER CONTAINING LACTATE SEGMENTS (Continued)
【摘要】 本文叙述了直接用乳酸与顺丁烯二酸酐及1.2—丙二醇合成含乳酸酯链节的不饱和聚酯的方法,以及含乳酸酯链节的不饱和聚酯与普通不饱和聚酯均交联后进行的加速水解对比实验,结果表明含乳酸酯链节的不饱和聚酯水解降解的程度较高,特别是用甲基丙烯酸甲酯交联者。
【Abstract】 sing lactic acid directly to react with maleic anhydride and 1, 2-propanediol,An unsatu-rated polyester resin was synthesized. The unsaturated polyester containing lactate segments was conducted a speed-up hydrolysis test in comparison with a normal un-saturated polyester resin. The unsaturated polyester containing lactate segments showed a higher degree of hydrolysis, especially the one crosslinked by methyl methacrylate.
