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: ##STR1## wherein each R, which can be the same or different, are alkyl radicals, R.sup.1 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.
Claims28
An extrudable composition comprising an olefin polymer and a silicone additive having the formula:
- ##STR23## wherein each R is an alkyl radical, R.sup.1 is a monovalent organic radical containing at least one ethylene oxide group, vicinal epoxy group or amino group and x and y each have a value of at least 1, said silicone additive being present in an amount sufficient to improve mechanical and/or optical properties.
An extrudable composition comprising a olefin homopolymer or interpolymer of an alpha olefin and a silicone additive having the formula:
- ##STR24## wherein R is a monovalent organic radical containing at least one ethylene oxide group, vicinal epoxy group or amino group and x and y each have a value of at least one, said silicone additive being present in an amount sufficient to improve mechanical and/or optical properties.
