Abstract:
The present invention provides a method comprising rotational molding a powdered polyolefin elastomer composition to form a skin, the composition formed by spray drying an aqueous polyolefin dispersion composition which is itself formed by melt blending a polyolefin composition comprising an olefin block copolymer, a dispersing agent, and water, wherein said aqueous dispersion preferably has a pH less than 12.
