Patent ID: 6962752

Claim:
A curable composition comprising: (A) a branched polyfluorodialkenyl compound of one of the formulae below: wherein m and n are, each independently, integers of 1 or greater, with an average value of m+n=2 to 200; (B) a branched polyfluoromonoalkenyl compound of formula (2): Rf 2 -(X′) a —CH═CH 2 (2) wherein X′ is —CH 2 —, —OCH 2 —, —CH 2 OCH 2 — or —CO—NR 1 —Y′—, Y′ is —CH 2 — or R 1 is hydrogen or a substituted or unsubstituted monovalent hydrocarbon group, a is 0 or 1, and Rf 2 is a group of formula (iv) or (v): F—[CF(CF 3 )CF 2 O] w —CF(CF 3 )— (iv) wherein w is an integer of 1 or greater that is smaller than the average value of m+n based on (A), or F—[CF(CF 3 )CF 2 O] x —CF(CF 3 )CF 2 OCF 2 CF 2 — (v) wherein x is an integer of 1 or greater that is smaller than the average value of m+n based on (A; (C) an organohydrogensiloxane compound with at least two hydrogen atoms bonded to silicon atoms within a single molecule; and (D) an effective quantity of a platinum group metal catalyst.
