摘　　要：初步探讨了不同的共混工艺过程对增韧效果的影响,结果表明,先ABS和PMMA共混,再加入PVC共混,增韧效果最佳,加工性能和热稳定性均有不同程度的提高。The effect of various blending processes on the toughening results of the PVC/ABS/PMMA blend system has been prelimenarily investigated. The experimental results show that the optimum is obtained by preblending ABS with the third component PMMA,then blending the mixture with PVC.In addition,the processability and heat stability are both improved to various degrees.
