Abstract:
An at least partially crosslinked elastomer comprising the reaction product of(1) functionalized elastomeric ethylene/ &agr;-olefin interpolymer containing reactive substituents with (2) a crosslinking agent (a) containing two or more reactive substituents differing from those contained in the functionalized elastomeric polymer, and (b) having a number average molecular weight less than about 2000, the &agr;-olefin containing from 4 to 10 carbon atoms when the elastomeric interpolymer is an ethylene/&agr;-olefin/diene terpolymer, each of the reactive substituents selected such that (i) those of the functionalized elastomeric interpolymer will react with those of the crosslinking agent to form covalent bonds which at least partially vulcanize the functionalized elastomeric interpolymer, and (ii) each of the reactive substituents is selected from the group consisting of carboxylic acid, carboxylic anhydride, carboxylic acid salt, carbonyl halide, hydroxy, epoxy, and isocyanate, â€ƒprovided that the reactive substituents of the functionalized elastomeric interpolymer are selected from the group consisting of carboxylic acid, carboxylic anhydride, carboxylic acid salt, carbonyl halide, hydroxy, and epoxy, wherein the reaction is a static vulcanization.
