Abstract
Abstract A crosslinking composition comprising a blend of at least two polyallylic esters of polycarboxylic acids, one of said esters being a diallylic ester of an alkyl, cycloalkyl, mixed alkylcycloalkyl or aralkyl dicarboxylic acid, the other of said esters being a polyallylic ester of an aromatic or heteroaromatic polycarboxylic acid or triallyl ester of isocyanuric acid. The crosslinking compositions are particularly useful as crosslinking coreactants for high temperature processing fluorocarbon polymers. The products resulting from the mixing of fluorocarbon polymers and blends of diallyl esters with triallyl or tetraallyl esters are particularly useful as coatings for wire products.
