<p>PURPOSE: Blends of syndiotactic and isotactic poly- alpha -olefin is provided to achieve an overall reduction of the coefficient of friction of films made from such blends. This may also be viewed as a reduction of characteristics or enhancement of "slip" characteristics of the films without inclusion of excessive additives, other than poly- alpha -olefins, into the polymer, its films, or other articles of the polymer. CONSTITUTION: The polyolefin-based compound, resin, mixture, or combinations thereof, providing products having reduced coefficient of friction, comprises: A) polyolefin other than syndiotactic poly- alpha -olefin; B) about 0.1% to about 70% syndiotactic poly- alpha -olefin; and C) about 0.01% to about 5% of: slip agent, anti-block agent, or combinations thereof.</p> |
