摘要
用种子乳液聚合的方法合成了一系列 PVA/ PBA乳胶互穿聚合物网络。提出了用相容程度来定量表征聚合物共混物中两组分的相容性。动态力学谱结果表明 ,乳胶双向互穿以及 BA同 AN共聚可极大地改善 PBA与 PVA的相容性和乳胶
A series of LIPNs based on poly(vinyl acetate) and poly(butyl acrylate) was synthesized by seed emulsion polymerization. It is suggested that the compatibility between two components in polymer blends can be quantitatively characterized by compatible degree based on dynamic mechanical spectroscopy(DMS). The results of DMS show that the compatibility between PVA and PBA and damping properties of LIPNs can be improved by latex bidirectional interpenetrating technique and the copolymerization of BA with AN.
