Abstract

The present invention relates to the preparation of a thermoplastic fluoropolymer blend composition exhibiting improved mechanical properties upon fabrication. The fluoropolymer blend composite on is produced by blending an emulsion latex of fluoropolymer (A) with an emulsion latex of fluorinated copolymer (B). Copolymer (B) emulsion has a small particle size, super high MW, and a low degree of crystallinity. The blending of the latex emulsions results in a morphology with small particles of copolymer (B) uniformly distributed within a matrix of fluoropolymer (A) in a manner that could not be achieved by a mere melt blending of the tow components.
