| 摘 要： | 分别研究了双甲基丙烯酸一缩二乙二醇酯、二缩三乙二醇酯、三缩四乙二醇酯为增塑剂的聚氯乙烯树脂糊的流变性能，并探讨了增塑剂含量，分子结构及环境温度对其影响。研究结果表明，三种体系的ＰＶＣ树脂糊都呈假塑性流体的特征，其表面粘度随双酯含量的增加，温度的升高以及双酯分子链结构中－ＣＨ２ＣＨ２Ｏ－链段的增长而逐渐降低。

| Abstract: | The rheologic behaviour of three kinds o f PVC pasty resins which di-,tri-,tetraethylene glycol dimethacrylate was used as a plasticizer was investigated.The effects ofcontent and molecular structure of three kinds of plasticizers and the temperature of environment on rheologic behaviour were discussed.The results showed that three kinds of pasty resins were showed fluid characteristics with paseudoplasticity,their apparent viscosity reduced gradually following by increasing of content,rising of temperature of environment and growing of-CH2CH2O-molecular-chain of polyethyleneglycol dimethacrylate. |
