Abstract
Articles having a Shore A hardness of 50 to 95 and made from polyolefin compositions comprising an ethylene-alpha-olefin interpolymer (random or block or a mixture of the two) are paintable without the need for a primer or other surface treatment with paints free of phthalate-based plasticizer and designed to paint SBS- or SEBS-type rubber based compositions. These polyolefin compositions are free of (1) phthalate-based plasticizer, (2) halogen-containing polymer, and (3) leachable, small polymeric units derived from styrene monomer. In addition, the content of the alpha-olefin in the polyolefin composition is at least 9.7 mole percent.
