摘要

为了将单体引入PVC基体，在四种溶剂(丙酮、甲基乙基酮、苯和甲苯)和含有0.1 wt.-%偶氮异丁腈的丙酮(10、25和50 wt.-%)的丙烯酸溶液中测试了PVC薄膜的膨胀行为。讨论了输运类型、扩散和渗透系数、吸附动力学和阿伦尼乌斯参数。

Hydrophilic PVC composite films obtained by in situ polymerization, 1 : Swelling studies

In order to introduce a monomer into a PVC matrix, the swelling behavior of PVC films was tested in four solvents (acetone, methyl ethyl ketone, benzene, and toluene) and in acrylic acid solutions in acetone (10, 25 and 50 wt.-%) containing 0.1 wt.-% azoisobutyronitrile. The type of transport, diffusion and permeation coefficients, sorption kinetics and Arrhenius parameters are discussed.
