摘　　要：总结了PVC树脂加工性能的评价方法,包括造粒评价试验、透明拉卷评价试验、动态热稳定性评价试验、高温老化评价试验、流变性能评价试验和分子质量分布测试。通过采用以上分析方法,可以在实验室内模拟下游生产过程,对PVC树脂粒料和透明片材等制品质量进行预测和评价。The evaluation methods for the processing performance of PVC resin were summarized,including granulation evaluation test,roll of transparent stretching PVC sheet test,dynamic thermal stability evaluation test,high temperature aging evaluation test,rheological performance evaluation test,and molecular weight distribution test.By using the above analysis methods,downstream production processes could be simulated in laboratory,and the quality of products such as PVC resin pellets and transparent sheets was predicted and evaluated.
