共混过程中MAH对PVC色泽的改善
关键字：MAH PVC 色泽
PVC的稳定性能包括PVC的热稳定性和色泽稳定性。PVC加工过程中，稳定剂除了要有一定的热稳定时间外，还要有较好的颜色。由于PVC加工过程中受热脱HCl形成共轭多烯烃，往往导致PVC发生颜色变化。我们通过共混，使马来酸酐（MAH）中的双键与PVC降解形成的共轭双键发生Diels-Alder加成反应，阻断共轭多烯烃的增长，改善PVC加工过程中的色泽。

增韧PVC透明树脂的理论和实验
关键字：透明树脂，PVC，增韧
透明树脂在塑料工业中占有重要的地位，广泛应用于日常生活的各个领域，如片材、板材、扭结薄膜、异型材等。聚氯乙烯（PVC）是世界总产量仅次于聚乙烯的第二个大品种通用塑料，它在机械稳定性、耐化学药品性和阻燃性等方面具有优异的性能，但由于其抗冲击性、热稳定性及加工方面的不足大大限制了其应用范围。为进一步拓展其应用领域，已有多种抗冲击改性剂开发上市。
