Critical surface tensions (γ c ) for blends of thermosetting fluorochemical methacrylates and thermosetting acrylate polymers are measured in their cured thermoset condition. Values of γ c depend on (1) the nature of the fluorochemical side chain and (2) the ratio of fluorochemical containing polymer to hydrocarbon polymer. The minimum value for γ c is found to occur at a fluorocarbon to hydrocarbon polymer ratio of 0.10 to 0.001. At higher and lower ratios (>0.1 and <0.001), the value for γ c increased. Thus, certain blends of fluorochemical methacrylate copolymer with hydrocarbon acrylate copolymer give lower γ c than either the hydrocarbon acrylate or the fluorochemical methacrylate copolymer.
