| 摘 要： | 测定了悬浮聚氯乙烯(S-PVC)树脂对增塑剂不同温度下的吸收量,采用扫描电镜表征了S-PVC不同增塑剂吸收条件下的结构形态.结果表明:S-PVC颗粒由多级粒子聚集而成,增塑剂主要通过各级粒子聚集体间的间隙沟槽进入PVC粒子内部完成润展与溶胀,S-PVC对增塑剂的吸收是具有时间和温度依赖性的四步吸收非定态过程.其吸收包括...

| Abstract: | Plasticizer absorption of suspended poly(vinyl chloride)(S-PVC) were determined under various time and temperature.The morphology of S-PVC grains under different plasticizer absorption conditions was characterized by scanning electron microscopy(SEM).The results showed that S-PVC grains were composed of multilevel particles,and there were grooves and pore channels among these particles.The S-PVC grains were spread and swelled by plasticizers entering through those grooves.The plasticizer adsorption of S-PVC... |
