Abstract
Described herein is a peroxide curable, highly fluorinated elastomer derived from (a) a fluorinated di-iodo ether compound of the following formula I: R—CF(I)—(CX)—(CXCXR)—O—R″f-O—(CXR'CX)—(CX)—CF(I)—R′wherein X is independently selected from F, H, and Cl; Rand R′are independently selected from F and a monovalent perfluoroalkane having 1-3 carbons; R is F, or a partially fluorinated or perfluorinated alkane comprising 1-3 carbons; R″is a divalent fluoroalkylene having 1-5 carbons or a divalent fluorinated alkylene ether having 1-8 carbons and at least one ether linkage; k is 0 or 1; and n, m, and p are independently selected from an integer from 0-5, with the proviso that when k is 0, n+m is at least 1 and p+q is at least 1; and (b) a fluorinated monomer.
