摘　　要：用PP-g-PMMA作为增容剂对PVC/PP共混体系进行增容改性.用紫外光辐照接枝的方法在聚丙烯(PP)上接枝极性单体甲基丙烯酸甲酯(MMA),讨论光照时间、单体用量和光敏剂用量对接枝率的影响,用IR对接枝产物进行表征,并使其作为PVC/PP共混体系的增容剂.实验结果表明:接枝物的加入对PVC/PP共混体系起到了增容作用,扫描电镜(SEM)也表明增容剂对共混体系有很好的增容作用.PP-g-PMMA was used as extender to modify PVC/PP blending system. UV photo-grafting on PP was performed by using MMA. The paper discussed the effects of copolymerization time, monomer concentration and sensitizer concentration on grafting rate. The graft copolymer of PP-g-PMMA was confirmed by IR and then was used as extender to PVC/PP blending system. Research results indicated that addition of grafting polymer improved significantly in extending to PVC/PP blending system. The SEM also proved the same results.
