Appeal No. 2001-1904
Application 09/240,450
(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 15 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 1:1 to about 1:0.005.
10. A method for reducing melt defects in melt processable
thermoplastic hydrocarbon polymer compositions which comprises
admixing a melt processable thermoplastic hydrocarbon polymer
with an effective amount of a polymer processing additive
composition comprising
(a) a fluorothermoplastic polymer containing units derived
from (1) 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, and
(b) a poly(oxyalkylene) polymer wherein the weight ratio is
the fluorothermoplastic polymer to the poly(oxyalkylene) polymer
is at least 1:1, mixing the polymer processing additive
composition and the hydrocarbon polymer for a time sufficient to
blend them together, and melt processing said admixture.
16. A processing additive composition comprising
(a) a fluorothermoplastic polymer containing units derived
from (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, and
