PROBLEM TO BE SOLVED: To provide a modifier for a polyolefin resin that imparts excellent wettability to water to a polyolefin resin base material without impairing mechanical strength.SOLUTION: The modifier for a polyolefin resin comprises: a modified polyolefin having at least one kind of functional group selected from the group consisting of an acid anhydride group, an epoxy group, an isocyanate group, a carboxyl group, a hydroxyl group, an amino group and a thiol group; and a sulfonic acid (salt)-modified polyolefin produced from the modified polyolefin and a sulfonic acid (salt) group-containing compound having a reactive functional group. A polyolefin resin composition comprises the modifier and a polyolefin resin. A molded article is produced by molding the composition. |
