Fuser member

Claim 1

A fuser member comprising a supporting substrate, and a outer layer comprised of a substantially uniform integral interpenetrating hybrid polymeric network comprised of a haloelastomer, a coupling agent, a functional polyorganosiloxane and a crosslinking agent wherein the functional polyorganosiloxane is derived from a compound having the formula: ##STR5## where R is independently an alkyl or alkenyl with from 1 to about 20 carbon atoms, or an alkylaryl or aryl group wherein the aryl of the alkylaryl or aryl group contains from 6 to about 30 carbons atoms and is optionally substituted with an amino, hydroxy, mercapto, or alkyl or alkenyl group having from about 1 to about 18 carbon atoms, the functional group A is independently an alkoxy or aryloxy group with from 1 to about 10 carbon atoms in each alkoxy or aryloxy groups, a hydroxy, or a halogen, and n is a number of from 2 to about 350 and represents the number of disubstituted siloxane monomeric units in the polyorganosiloxane; wherein the hybrid polymeric network is formed by the sequential reaction of the haloelastomer with a dehydrohalogenating agent, reaction with the coupling agent, condensation with the functional polyorganosiloxane, and crosslinking with the crosslinking agent.
