Vinyl chloride/ethyl acrylate copolymer (VC/EA) was blended with surface modified nanometer calcium carbonate (n-CaCO3) to form a masterbatch which was subsequently introduced into poly(vinyl chloride) (PVC).

• 通过对纳米碳酸钙(n-CaCO3)表面改性及其对聚氯乙烯(PVC)、氯乙烯-丙烯酸乙酯共聚物(VC/EA)、 n-CaCO3三元复合体系加工工艺的考察,研制了(VC/EA)/n-CaCO3复合母粒改性的PVC材料,并对其力学性能进行了研究。
