Abstract:
A melt processable polymer composition comprising:a major amount of a melt processable thermoplastic hydrocarbon polymer; and a minor amount of a processing additive composition comprising: (a) a fluorothermoplastic polymer containing units derived from a monomer charge of (i) vinylidene fluoride and, (ii) at least two separate ethylenically unsaturated copolymerizable fluorinated comonomers, and (iii) optionally at least one low molecular weight non-fluorinated alpha olefin monomer provided that when the low molecular weight non-fluorinated alpha olefin monomer is present, the vinylidene fluoride comprises at least about 20 weight percent of the monomer charge used to prepare the fluorothermoplastic polymer; and (b) a poly(oxyalkylene) polymer wherein the weight ratio of said fluorothermoplastic polymer to said poly(oxyalkylene) polymer is from about 1:0.11 to about 1:0.005.
