Abstract
Abstract Olefin polymer compositions containing silicone additives which can be extruded through relatively narrow die gaps at commercial extrusion rates to provide film material characterized by improved mechanical and optical properties. The silicone additives have the formula: <IMAGE> wherein each R, which can be the same or different, are alkyl radicals, R1 is a monovalent organic radical containing at least one ethyleneoxide group, vicinal epoxy group or amino group and x and y, which can be the same or different, each have a value of at least one.
