The conditions to produce PP-g-PVOH with the highest SP 60% were: ethyl alcohol/butyl alcohol=30/70, NaOH%=0.5%, refluxing at 90℃ for 16hr.FTIR confirmed graft and saponification reactions, and it was identified that graft reaction influence porosity and morphology very little, but microparticles in PP granule were sightly swelled. There was a peak relationship between melt flowing index and GP and the flowing property was decreased with sponification reactions.

红外光谱证实了接枝和醇解反应的发生；孔隙率和PP粒子内部形貌观察的结果表明，接枝反应对粒子孔隙率的影响不大，但其内部微粒有所溶胀；接枝率增大，熔融指数呈现先上升后下降的趋势，对材料力学性能的研究表明，随PP-g-PVAc接枝率的增加，材料的断裂伸长率和拉伸强度先增加后降低，拉伸模量逐渐增加，材料的缺口冲击强度降低。

The crystallization temperature and the crystallinity of PP increase due to the nucleation effect of sodium benzoate, which contributed to the improvement of the rigidity and heat resistance of the composites.

研究表明，RPS对PP具有一定的促进结晶的作用，且含有苯甲酸钠的yRPS对PP的成核作用较之未加苯甲酸钠的nRPS更为显著，故RPS的加入提高了PP的结晶温度、熔融温度和结晶度。

The data of mechanical properties test proved that the composite materials compounded with 0.39~0.46um PS organic rigid particles at 0.2% and PP have excellent strength and toughness. SEM photograph found that the organic rigid particles were separated into 60~80nm size in the composite by melting process, which has belter toughness compare with the PP compounded with ultra-fine organic rigid particles.

用2％粒径为0.39～0.46um的XPS复合PP，经力学性能测试，有最好的增韧效果；SEM扫描电镜发现，经热加工的复合材料中最小的有机刚性粒子粒径可部分分散到60～80nm，该复合材料比超细有机刚性粒子复合的PP有更好的冲击韧性。
