Patent ID: 6875823

Claim:
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 resins, wherein said melt-kneading is carried out in an extruder having a former melt-kneading zone and a latter melt-kneading zone, the temperature in the latter melt-kneading zone being higher than that in the former melt-kneading zone.
