(57) [Abstract] [PROBLEMS] To provide a vinyl-based copolymer having an epoxy group capable of improving the processability, rigidity and surface property of a polyolefin, and a polyolefin-based resin composition containing the copolymer. . [Structure] A vinyl-based copolymer having an epoxy group, which mainly contains an unsaturated glycidyl compound and a vinyl compound. In this vinyl copolymer having an epoxy group, the unsaturated glycidyl compound is 0.01 to 50% by weight, The vinyl compound is contained in a proportion of 50 to 99.99% by weight. |
