ABSTRACT:
This invention relates to a composition and method of modifying the surface of a polymeric to produce a film or article with a reduced coefficient of friction (COF) and improved release properties. The reduced coefficient of friction improves both the slip and anti-blocking properties of the material as well aiding in processing of the polymeric material. Additionally, the invention improves demolding and release of the polymeric material from other polymeric surfaces or adhesives as well as metal molding surfaces.
