Abstract:
通过巯基与聚氯乙烯（PVC）氯原子的亲核反应将羧基引入PVC大分子链，再利用环氧脂肪酸甲酯与羧基之间的反应，通过化学键将其连接入PVC大分子链，实现对PVC内增塑.用傅里叶红外（FTIR）、核磁共振（1H-NMR）、示差扫描量热法（DSC）对改性产物进行了表征.FTIR、1H-NMR结果表明，环氧脂肪酸甲酯成功共价连接到了PVC大分子链上，接枝率为1.2mol%；DSC测试结果显示，所采用的环氧脂肪酸甲酯改性PVC方法能有效降低PVC的玻璃化转变温度（Tg），5.6wt%的增塑剂可将PVC的Tg从81.4℃降至37.8℃；增塑剂耐溶剂抽出性与耐挥发性实验结果表明，环氧脂肪酸甲酯在测试时间内无损失，增塑剂迁移得到彻底抑制.
