Water absorptive resin compositions and process for producing the same

摘要

The water absorptive resin composition of this invention is a composite comprising 5 to 95% of a carboxylate-containing water absorptive resin and 95 to 5% of a glycidyl group-containing polyolefin. The process for producing this water absorptive resin composition according to this invention comprises kneading a carboxylate-containing water absorptive resin and a glycidyl group-containing polyolefin under the kneading conditions of a kneading temperature of 120 DEG to 280 DEG C. and a residence time in a kneader of 2 seconds or more. According to this invention, there is produced a composition of excellent water absorptivity, shape maintenance and moldability into a film.
