Title:
TETRAFLUOROETHYLENE COPOLYMERS
Document Type and Number:
WIPO Patent Application WO/2013/189826
Kind Code:
A1
Abstract:
The invention pertains to a tetrafluoroethylene (TFE) copolymer comprising recurring units derived from at least one per(halo)fluoroolefin different from TFE [monomer (F)] [monomer (F)], in an amount of 0.005 to 0.250 % moles, with respect to the total moles of the copolymer, wherein a particular relation between monomer content and amorphous index is satisfied, and to a process for its manufacture by emulsion polymerization in the presence of certain cyclic surfactants.
