Abstract
An improved method for preparing cross-linked polymers is disclosed, in which at least one alkyl or alicyclic substituent attached to an aromatic radical in the polymer acts as a functional site for oxidative cross-linking. The polymer may be extruded or solvent-deposited directly onto electrical conductors prior to cross-linking. The polymer film may then be cross-linked when exposed to an oxidizing agent and heated at a temperature within the range from the polymer's glass transition temperature to just below its degradation temperature.
