橡胶含量对ABS树脂及接枝共聚物结构的影响

Effect of rubber content on ABS resin and graft copolymer structure

采用乳液聚合方法,通过改变PB含量合成了系列具有不同接枝率的接枝共聚物,与SAN树脂进行共混造粒制得ABS树脂。考察了不同PB含量的接枝共聚物接枝率的情况及不同接枝共聚物ABS树脂微观结构及相应的接枝共聚物微观结构。

With emulsion polymerization process,series of graft copolymers of different grafting ratio were synthesized by changing the content of PB,which then was blended with SAN and granulated,and ABS resin was obtained. The grafting ratio under different PB content as well as the different graft copolymer ABS resin microstructure and the corresponding graft copolymer microstructure were investigated.
