ABSTRACT:
Fluorinated polymers for use per se or in a blend with compatible homopolymer or copolymer which is not fluorinated, for providing a low surface energy (anti-stick, non-wetting, low friction) surface which is stable on immersion in water, has a weight average molecular weight ranging from 10.sup.3 to 10.sup.6 and comprises backbone containing (a) methylene groups and (b) side chain bearing groups with side chain on each side chain bearing group having the formula --Q--(CF.sub.2).sub.q F wherein Q comprises alkylene moiety and wherein the fluoroalkyl group attached to Q is spaced by r atoms from the atom in the backbone to which Q is attached, wherein q ranges from 6 to 15, r ranges from 6 to 18, and the ratio of q to r ranges from 0.6:1 to 1.8:1. Preferred fluorinated polymers include semifluorinated block copolymers of modified isoprene and styrene and semifluorinated ionenes.
