The present invention relates to polymer compositions having improved adhesion for coating materials. The compositions include 40-90% by weight of a polyolefin, 10-50% by weight of a first rubber component and 1-20% by weight of a second rubber component. The first rubber component is preferably an ethylene propylene diene rubber having a weight average molecular weight of 50,000 to 300,000, while the second rubber is an ethylene-propylene diene rubber having a number average molecular weight of about 2,000 to 10,000.
