ABSTRACT:
Additives which have low loss factors and high dielectric constants are added to olefin/carbon monoxide copolymers, thereby synergistically enhancing the beneficial thermal response of the copolymers to the action of radio frequency energy, especially microwave energy. The additives may be, e.g., metal salts, metal oxides, and metal-organic compounds. The copolymer is preferably comprised of ethylene/carbon monoxide (E/CO) or a terpolymer of E/CO/M, where M represents minor amounts of one or more other olefinically-unsaturated monomers which are copolymerizable with ethylene.
