中文摘要：
研究了几种生产工艺聚氯乙烯（PVC）糊树脂分子量及分布对增塑糊黏度及稳定性能的影响。结果表明：相同颗粒形态糊树脂中，分子量越大，黏度越小，分子量大小与增塑糊存放稳定性无明显规律；分子量大小比聚合度更能反映与增塑糊黏度的对应关系。
英文摘要：
Effect of PVC molecular weight on viscosity and its stability over time of plastisol was studied. The results showed that the higher the molecular weight was,the lower the viscosity was in the same PVC particulate morphology. It had no obvious law of molecular weight on viscosity stability of plastisol. It was more accurate to describe the corresponding relationship of viscosity using molecular weight than degree of polymerization.
