| 摘 要： | 用IR及DSC研究了（侧基含有过氧键的聚苯乙烯）与PP之间的反应，考察了反应温度、苯乙烯单体等对共混过程的影响。结果表明：RPS/PP共混体系中，PP降解严重，而PP/RPS/Rt（苯乙烯）共混体系可有效地抑制降解，反应生成的PP-g-PS对PP/PS合金具有增容作用，提高了合金的力学性能。

| Abstract: | The reaction between RPS (having peroxy group as a pendent group along polystyrenic backbone) and polypropylene was studied by IR and DSC. Effects of reaction temperature and styrene monomer on the blending were evaluated. The results showed that the system of PP/RPS would result in the degradation of PP seriously, but the situation could be improved by adding styrene monomer during melt blending. The PP - g - PS resulted from PP/PS/St melt blending system has a compatibilizing effect on PP/PS blends , thus improving the mechanical properties of the blends. |
