Abstract (en)

[origin: WO2016100420A1] Described herein is a curable partially fluorinated polymer composition and a method thereof. The composition comprising: (i) a partially fluorinated amorphous fluoropolymer, wherein the partially fluorinated amorphous fluoropolymer comprises carbon-carbon double bonds or is capable of forming carbon-carbon double bonds along the partially fluorinated amorphous fluoropolymer chain; (ii) 1 to 10 parts of a curing agent per 100 parts of the partially fluorinated amorphous fluoropolymer wherein the curing agent is of the formula CX1X2=CX3-L-M, wherein X1, X2, and X3 are independently selected from H, Cl, and F and at least one of X1, X2, and X3 is H; L is a bond or a linking group; and M is a nucleophilic group; (iii) an acid acceptor; and (iv) an organoonium compound.
