摘要
采用正电子湮没对添加聚丙烯酸酯类（ACR）增韧粒子的聚氯乙烯（PVC）共混材料进行了研究。结果表明，随ACR比例的上升，PVC结构中氯原子的强电负性受到削弱，PVC主链区和结构改性剂中自由体积缺陷尺寸及数量增加。
Polyvinyl chloride (PVC) blended material which was filled with ACR toughenparticles was studied by positron annihilation technique (PAT). The result showedthat, with the increasing proportion of ACR particles in the material, the stroryelecbegativity of chloride atom in PVC decreased, and the dimension and quantityof free volume defects in the main- chain of PVC increased.
