PURPOSE:A molded article of a polyolefin resin contaning a small amount of a specific compound is treated with plasma on its surface to remarkably improve its surface properties such as paint applicability and adhesion. CONSTITUTION:A polyolefin resin such as a propylene block copolymer is combined with 0.01-2pts.wt. per 100pts.wt. of the resin, of at least one of compounds of the formula (R1 is 1-12C alkyl; R2 is H, group that can combine through N and C; R3 is group that can bind with a carbon in a heterocyclic ring through C, O or N) such as sebacic acid, when necessary, along with a variety of additives, polymers and inorganic fillers. Then, the resultant composition is made into a molded article and the article is treated with plasma to effect the objective surface treatment. USE:Parts of cars, electric appliances for domestic purpose and daily goods.
