摘要
本文用毛细管流变仪和ＤＳＣ 研究了改性聚丙烯对ＰＰ／ＰＰｇＭＡ 共混体系流变性和热行为的影响。结果表明，在ＰＰ中加入固相接技反应得到的ＰＰｇＭＡ，在剪切应力作用下，粘度下降很快；并且该体系的熔点和熔程都有显著变化。
s The effect of PP g MA on rheological behaviour and thermal properties was studied by means of capillary rheometer and DSC method.The resutls showed that the viscosity of melt PP/PP g MA suddenly decreased with adding PP g MA from solid graft reaction and the effect of shear stress,the melting zone and melting point obviously changed.
