ABSTRACT:
There is provided a process for producing a modified polyolefin resin, which comprises the steps of:(1) blending at least the following components (A) to (D) to produce a blend:(A) 100 parts by weight of a polyolefin resin,(B) from 0.1 to 20 parts by weight of a compound having an epoxy group and an unsaturated bond,(C) from 0.01 to 20 parts by weight of an organic peroxide having a decomposition temperature of from 50 to 115° C., at which temperature a half-life thereof is 1 minute, and(D) from 0 to 20 parts by weight of an organic peroxide having a decomposition temperature of from 150 to 200° C., at which temperature a half-life thereof is 1 minute, and(2) melt-kneading said blend to produce a modified polyolefin resin.
