Abstract:
1. A method for the preparation of a molded article formed of an olefin polymer comprising: a) providing a particulate molding feedstock comprising a mixture of a particulate olefin polymer composition and a densification aid comprising a polyether-block copolyamide, wherein the particulate molding feedstock comprises from 0.001 to 1 weight percent of the densification aid; b) introducing said molding feedstock into the mold cavity of a rotational mold; c) rotating said mold about at least one axis; d) during the rotation of said mold, heating said olefin polymer composition incorporating said densification aid to a temperature sufficient to provide a molten state of said polymer composition to form a molded article configured to the shape of said mold cavity; e) thereafter cooling said molten polymer composition within the confines of said mold cavity to a temperature effective to solidify said olefin polymer composition within the confines of said mold cavity; and f) retrieving said solidified molded article from said mold cavity.
