A composition having repellency to low surface tension fluids comprising a material prepared by forming a mixture of a polymer selected from the group consisting of polyolefin, polyamide, polyester, polyacrylate, and blends and copolymers thereof, and a fluorochemical compound comprising a fluorocarbon/hydrocarbon ester of the formulae: Rf-O-C(O)-R1 or Rf-C(O)-O-R1 wherein Rf is selected from the group consisting of: 1) F(CF2)x-(CH2)m wherein x is from about 4 to about 20 and m is from about 0 to about 6; and 2) F(CF2)x-SO2N(R2)-R3 where x is a positive integer from about 4 to about 20, R2 is an alkyl radical of from about 1 to about 4 carbon atoms, R3 is an alkylene radical of from about 1 to about 12 carbon atoms; and R1 is an aliphatic hydrocarbon having from about 12 to about 76 carbon atoms; and provided that said fluorochemical compound is other than perfluoroalkylethyl stearate; and melt extruding the mixture. |
