Patent ID: 7375157

Claim:
Melt-processible polymer composition comprising (a) a non-fluorinated melt-processible polymer; and (b) a fluoropolymer derived from the copolymerization of: (1) at least 20% by weight of vinylidene fluoride, (2) one or more fluorinated monomers, and (3) one or more modifiers selected from (i) olefins having a bromine or iodine atom bonded to a carbon of the double bond of the olefins, (ii) olefins corresponding to formula (IV): X a 2 C═CX a —R f—(X b ) r (IV) wherein each X a independently represents hydrogen, fluorine, or chlorine, R f is a perfluoroalkylene group, a perfluorooxyalkylene group or a perfluoropolyether group, X b is Br or I and r is 1, 2 or 3 and (iii) mixtures thereof, and wherein the one or more modifiers are included in an amount not more than 1.0% by weight and is sufficient to form long chain branching in the fluoropolymer without the formation of gels.
