摘要
研究了分子量及其分布对注射成型聚丙烯样条的密度、结晶度、拉伸性能、冲击性能的影响．不同分子量与分子量分布的聚丙烯样品由化学控制降解制得，用数学方法分析了实验数据与分子量分布之间的量化关系．
In this paper,the effect of molecular weight and polydispersity on the density, degree of crystallization, tensile and impact properties of injection model polypropylene bars has been studied. The polypropylene specimens having different MWD were prepared by controlled chemical degradation. Mathematical analysis method was used to correlate the experimentally measured values with the MWD characteristics.
