    摘要： A fuser member having a substrate, an outer polymeric layer, an outer polymeric layer, and a release agent material coating on the outer polymeric layer, wherein the release agent material coating includes a copolymer having the following formula: wherein A and B are the same or different, and each represents —R4—X, wherein R4 represents an alkyl group having from about 1 to about 10 carbons, X represents —NH2 or —NHR6NH2 with R6 representing an alkyl group having from about 1 to about 10 carbons; R1 and R2 are the same or different and each is selected from the group consisting of an alkyl having from about 1 to about 25 carbons, an aryl having from about 4 to about 10 carbons, and an arylalkyl; R3 and R5 are the same or different and each is selected from the group consisting of an alkyl having from about 1 to about 25 carbons, an aryl having from about 4 to about 10 carbons, an arylalkyl, and a substituted diorganosiloxane chain having from about 1 to about 500 siloxane units; b and c are numbers and are the same or different and each satisfy the conditions of 0≦b≦10 and 10≦c≦1,000, but both b and c must not be 0 at the same time; d and d′ are numbers and are the same or different and are 2 or 3, and e and e′ are numbers and are the same or different and are 0 or 1, and satisfy the conditions that d+e=3 and d′+e′=3, f is a number of from about 0 to about 10, and b+c+f is from about 0 to about 10.

    摘要： Disclosed is a composition comprising a crosslinked product of a liquid composition which comprises (a) a fluorosilicone, (b) a crosslinking agent and (c) a thermal stabilizing agent comprising a reaction product of (i) a cyclic unsaturated-alkyl-group-substituted polyorganosiloxane, (ii) a linear unsaturated-alkyl-group-substituted polyorganosiloxane, and (iii) a metal acetylacetonate or metal oxalate compound. The crosslinked fluorosilicones can be employed as intermediate or outer layers of electrostatographic fuser members, electrostatographic intermediate transfer belt materials and the like. They are useful in applications wherein materials possessing desirable release characteristics, surface energies, electrical characteristics, oil resistance properties, or solvent resistance properties exhibited by fluorosilicone elastomers are desirable. They are also useful in applications wherein fluorosilicones are exposed to high temperatures, since the stabilizing components reduce the generation of toxic effluents such as trifluoropropionaldehyde and formaldehyde, which can form when methyl-methyl crosslinking of the polymer occurs, and increase temperature stability.
