摘要

A water-swellable rubber (WSR),compatibilized by the amphiphilic graft copolymer,has been prepared by blending chlorohydrin rubber (CHR) with crosslinked polyacrylate 9CPA),poly(vinyl alcohol)-g-poly(butyl acrylate) (PVA-g-PBA),precipitated silica (PSA),and poly(ethylene glycol) (PEG).The WSR was characterized by scanning electron micrography (SEM).The dependence of the water-absorbing ratio by weight,the water-swelling ratio by volume,and the percentage loss by weight on PVA-g-PBA and crosslinked polyacrylate contents was investigated.The effect of PVA-g-PBA and crosslinked polyacrylate contents on second water-swelling behaviors and long-term water-retention behaviors were also studied.
