| 摘 要： | 通过乳液聚合方法制备了两种不同粒径（分别为270nm和80nm）的甲基丙烯酸甲酯/丁二烯/苯乙烯（MBS）核壳改性剂，与聚氯乙烯（PVC）进行熔融共混，得到了PVC／MBS共混物。对PVC／MBS共混物力学、光学等方面的性能及其形变机理分别进行了考察。结果表明：PVC／MBS共混物的脆-韧转变温度（BDT）和拉伸性能均随着MBS粉料粒径的增加而增加；但是光学测试则表明MBS粒子对改善PVC基体的光学性能的效果却随MBS粉料粒径的增加而降低；透射电镜（TEM）的分析表明大粒径的MBS粉料能促使橡胶粒子产生空洞化，而由小粒径的MBS粉料制备的PVC／MBS共混物没有观察到橡胶粒子空洞化的产生。

| Abstract: | Methylmethacrylate/butadiene/styrene (MBS) core-shell particles with different sizes (270 nm,80 nm) were synthesized via emulsion polymerization, which was employed to blend with PVC via melt mixing. The mechanical properties, optical properties and the deformation behaviors of PVC/MBS blends were investigated. Larger particles size of MBS resulted in higher tensile strength, but higher brittle-ductile transition (BDT) temperature and lower transparency. TEM showed that the MBS with large particle sizes could promote cavitation, however, no cavitation was observed in case of small particle sizes. |
