PVC用ACR冲击改性剂的研制和应用性能

Preparation and Applied Performance of ACR as Impact Modifier for PVC

以甲基丙烯酸甲酯(MMA)、丙烯酸乙酯(EA)、丙烯酸丁酯(BA)和苯乙烯为单体,制备了用作冲击改性剂具有核-壳结构的ACR共聚物,并对其应用性能进行了评价。结果表明,此ACR冲击改性剂明显改善了PVC的冲击性能,同时也改善了PVC的加工性能。

The ACR core/shell copolymer as impact modifier was prepared from methyl methacrylate, ethyl aery-late , butyl acrylate and styrene. The applied performances of the ACR impact modifier were evaluated. The results showed that the impact resilience and processability of PVC were improved by the ACR impact modifier.
