Abstract:
1. A method for the preparation of a molded article formed of an olefin polymer comprising: a) providing a molding feedstock comprising a particulate olefin polymer composition; b) providing a densification aid comprising a polyether-block copolyamide; c) introducing said olefin polymer composition and said densification aid in an amount of no more than 1 weight percent based upon the amount of said olefin polymer into a mold cavity configured to provide a mold of a desired shape; d) heating said olefin polymer composition in the presence of said densification aid in said mold cavity to a temperature sufficient to provide a molten state 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.
