研究了聚氯乙烯（PVC）与甲基丙烯酸甲酯-丁二烯-苯乙烯（MBS）接枝共聚物共混物的微孔化机理和力学性能。结果发现，增韧效果是独立的类型的微孔机制发生在共混物。MBS颗粒的内部空化和PVC/MBS界面处的脱粘都缓解了三轴张力，从而促进了PVC基体的剪切屈服。
The microvoiding mechanisms and mechanical properties of a blend of poly(vinyl chloride) (PVC) with methyl methacrylate-butadiene-styrene (MBS) graft copolymers are investigated. It is found that the toughening effect is independent of the type of microvoiding mechanism occurring in the blend. Both internal cavitation of the MBS particles and debonding at the PVC/MBS interface relieve the triaxial tension and thereby promote shear yielding of the PVC matrix.
