ABSTRACT:
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.sup.1 --A--Si(R.sup.2 R.sup.3)--O--[Si(R.sup.4 R.sup.5)--O].sub.n --Si--(R.sup.6 R.sup.7)--A--R.sup.8, and forming the mix of polymer and additive to a desired form. R.sup.1 and R.sup.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--(CH.sub.2).sub.3 --, and --C(O)--NH--(CH.sub.2).sub.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.
