ABSTRACT:
A composition of matter formed by melt-blending a thermoplastic polymer and from about 0.01% to less than about 1.0%, by weight, of an additive comprising a polyfluoroalkylsiloxane, the additive having a lower surface energy than that of the polymer, and the blending resulting in a substantially homogenous admixture of the polymer and the additive. The admixture, upon cooling, results in a solid composition wherein a concentration of the additive through a cross-section of the solid composition is lower in the interior thereof and higher at the surfaces thereof.
