<p>A method for forming a polymer with a decreased surface energy. The method comprises the steps of mixing from about 99.5% to about 95.0% of a polymer selected from the group consisting of polyolefin and polyester with from about 0.5% to about 5.0% of a surface modifying agent having the structure R<1>-A-Si(R<2>R<3>)-O-[Si(R<4>R<5>)-O]n-Si-(R<6>R<7>)-A-R<8,> and forming the mix of polymer and additive to a desired form. R<1> and R<8> are selected from the group consisting of derivatives of aliphatic or aliphatic/aromatic alcohols or mono-acids with a molecular weight of between about 250 to about 600 daltons, and A is selected from the group consisting of -O-, -NH-C(O)-NH-(CH2)3-, and -C(O)-NH-(CH2)3-. The agent is substantially intimately mixed with the polymer. The present invention also discloses a polymeric material with an increased surface energy prepared according to the method, a release liner, a method for forming injection molded or blow molded polymeric articles where the articles have a non-fugitive release agent, and a film extrusion processing aid comprising an additive for compounding with a polymeric composition being extruded.</p> |
