Abstract
A primer composition for olefin resins is disclosed, comprising Components (A) and (B): (A): a resin having an acid group prepared by graft polymerizing .alpha.,.beta.-unsaturated carboxylic acid or its anhydride onto a styrene-butadiene-styrene block copolymer or its hydrogenated product. (B): an organic solvent capable of dissolving the resin of Component (A).
Claims11
A method for coating a polyolefin substrate, consisting of:
- (I) applying to said substrate an acidic-group containing resin prepared by polymerizing an .alpha.,.beta.-unsaturated carboxylic acid or its anhydride onto a styrene-butadiene-styrene block copolymer or its hydrogenated product wherein said resin is dissolved in an organic solvent at a resin concentration of 5-50 weight percent, and
- (II) obtaining a coated polyolefin substrate.
A method for coating a polyolefin substrate, consisting of applying to the said polyolefin substrate, a composition comprising (A) a mixture of (i) 1 to 90 wt. % of an acidic group-containing resin prepared by graft polymerizing an .alpha.,.beta.-unsaturated carboxylic acid or its anhydride onto a styrene-butadiene-styrene block copolymer or its hydrogenated product, and (ii) 99 to 10 wt. % of a maleic anhydride-grafted chlorinated polypropylene, and (B) an organic solvent capable of dissolving (A).
