Abstract
This invention relates to a composition and method of modifying the surface properties of polymers to produce a film or article with improved surface properties by utilizing an organo-modified polyslioxane additive. The improved surface properties for the polymer include a reduced coefficient of friction, which assists the slip and anti-blocking properties of the material, as well aiding in processing of the polymeric material. Additionally, the additive composition of this invention improves demolding and release of the polymer material from other polymeric surfaces or adhesives as well as metal molding surfaces, and allows the entire film or article formed of the polyolefin and additive to be recycled.
