Abstract
This invention relates to a graft polyolefin which is obtained by a method comprising the steps of: (a) dissolving or dispersing, in an organic solvent, an acid anhydride-modified amorphous polyolefin which comprises propylene and butene as polymerizable components, thereby preparing its solution or dispersion; (b) adding a hydroxyl group-containing radical polymerizable monomer to the solution or dispersion, and allowing the acid anhydride-modified polyolefin to react with the hydroxyl group-containing radical polymerizable monomer; and (c) effecting graft polymerization by adding at least one radical polymerizable monomer and a radical initiator. This invention also relates to a resin coating composition which contains this graft polyolefin as a solid content.
