α-甲基丙烯酸接枝ABS的性能表征及应用

Properties of Polymethacrylic Acid (PMMA) Grafted Acrylonitrile-butadiene-styrene Terpolymer (ABS) and Its Application

通过热失重分析、氧指数等方法对甲基丙烯酸 ABS接枝共聚物(ABS g PMMA)的阻燃性能进行了表征。结果表明接枝甲基丙烯酸能够在一定程度上提高ABS的阻燃性能。而力学测试和扫描电镜的结果也证明ABS g PMMA接枝物的适量添加对ABS与溴 锑协同阻燃剂组成的阻燃体系有一定的增容作用。

The graft copolymerization of α-methacrylic acid onto ABS improved the flamed retardancy of ABS in a certain degree.The ABS grafted with α-methacrylic was found to be good compatibilizer for ABS/PC alloy or flame retarded ABS with bromide-antimony oxide.
