摘要
通过对均聚、共聚和高熔体强度PP的离模膨胀、不同温度下的熔体强度、结晶温度和拉伸粘度进行了测量、比较和表征 ,揭示了熔体强度对PP加工性能的影响因素 。
The determination, comparision and characterization of the die swell ratio, the melt strength under different extrusion temperature, the crystallization temperature and the tensile viscosity were conducted between homopolymer PP, block-copolymer PP and high-melt-strength PP to evaluate the effects of melt strength on the processibility of PP, thus providing basis for the processing and applications of PP.
