| 摘 要： | 利用聚氯乙烯的化学反应制备了丙烯酸代聚氯乙烯，用此与丙烯酸共聚，合成了聚氯乙烯接枝聚丙烯酸接枝共聚物；利用红外光谱仪表征了它们的化学结构，用此接枝共聚物作为ＰＶＣ／ＰＡＡ供混体系的增容剂；利用ＤＳＣ等实验方法研究了ＰＶＣ／ＰＡＡ增容体系的热性能及力学性能。实验结果表明，所合成的接枝共聚物能够显著提高聚氯乙烯与聚丙烯酸的相容性，当接枝率为０．５７时，增容效果最佳。

| Abstract: | By the chemical reaction of poly(vinyl chloride)(PVC), acrylic poly(vinyl chloride) is prepared. It is copolymerized with acrylic acid and the grafted copolymer of PVC g poly(acrylic acid)(PAA) is prepared. Its chemical structure is identified by IR and used as the compatibilizer for PVC/PAA blends. The thermal and mechanical properties of the compatibized PVC/PAA blends are determined by means of DSC and other methods. The results show that PVC g PAA can improve the compatiblity of PVC/PAA obviously. The compatiblity of PVC g PAA to PVC/PAA becomes best while its graft rate is 0 57 |
