<p>A polymer processing aid composition, a melt processable thermoplastic hydrocarbon polymer composition that uses the polymer processing aid, and a method of improving the melt processability of a thermoplastic hydrocarbon polymer are provided. The polymer processing aid composition comprises a major amount of a fluorothermoplastic polymer that comprises interpolymerized units derived from vinylidene fluoride, at least one ethylenically unsaturated copolymerizable fluorinated monomer, and, optionally, at least one low molecular weight non-fluorinated olefin monomer.</p> |
