提出了两个模型来预测不饱和聚酯树脂/苯乙烯体系固化过程中发生的体积变化。这些模型能够解释加工过程中的热膨胀/收缩和聚合收缩。一种基于转换的模型是通过结合差示扫描量热法和膨胀法的实验结果开发的。第二个模型是基于自由基浓度，并开发了使用电子自旋共振光谱和荧光测量的结果。从这两个模型得到的预测与实验结果进行了比较，并获得合理的协议。
Two models were proposed to predict the volume changes that occur during the cure of unsaturated polyester resin/styrene systems. These models are able to account for both thermal expansions/contractions and polymerization shrinkage during processing. One model, which is based on conversion, was developed by combining experimental results from differential scanning calorimetry and dilatometry. The second model is based on radical concentration, and was developed using results from electron spin resonance spectroscopy and dilatometry. Predictions obtained from both models were compared with experimental results and reasonable agreement was obtained.
