本文回顾了最广泛使用的模型，解释增塑剂如何使PVC的灵活性。这些模型包括凝胶、润滑性和自由体积理论;动力学理论;以及基于增塑剂结构预测增塑剂将在柔性PVC化合物中降低聚合物玻璃化转变的数学模型。由于塑化结果从增塑剂和聚合物之间的相互作用，已被用来研究这些相互作用的强度或持久性（或两者）的方法也简要讨论。经常用于研究增塑剂-PVC相互作用的工具包括红外和核磁共振光谱、压缩和湿老化测试、动态力学分析、扭矩流变仪测试、增塑剂-树脂清亮点温度测量、通过热阶段测量的增塑溶胶凝胶化/熔融等。J.乙烯基添加剂一个人，15：219-223，2009. (C)2009年塑料工程师学会
This paper reviews the most widely used models for explaining how plasticizers render PVC flexible. These models include the gel, lubricity, and free volume theories; kinetic theories; and mathematical models which predict on the basis of plasticizer structure how much a plasticizer will lower the polymer glass transition in a flexible PVC compound. Since plasticization results from interactions between plasticizer and polymer, methods which have been used to study either the strength or the permanence (or both) of those interactions are also briefly discussed. Tools which have often been used to study plasticizer-PVC interactions include infrared and nuclear magnetic resonance spectroscopy, compression and humid-aging tests, dynamic mechanical analysis, torque rheometer tests, plasticizer-resin clear point temperature measurements, plastisol gelation/fusion by hot stage measurements, and others.
