Melt additives for low surface-energy applications

Abstract

Fluorine-free and silicone-free extruded release liner for silicone adhesives that is stable at high temperatures, has advantageous surface energy characteristics, has minimal impact on adhesive performance, and has minimal environmental impact comprising a composition that includes a thermoplastic polymer and a polymer melt additive represented by the structure (I) where Y is a bivalent carbonyl- or sulfonyl-substituted arylene or aliphatic group, each Z is independently a single bond or an arylene group, and each Q is independently a hydrocarbyl or a heterohydrocarbyl group. Methods of preparing such compositions and additives are provided.
