Johnson, R; Steinberg, M

This invention relates to a high molecular weight terpolymer of ethylene, sulfur dioxide and carbon monoxide stable to 280 C and containing as little as 36 mol % ethylene and about 41--51 mol % sulfur dioxide; and to the method of producing said terpolymer by irradiation of a liquid and gaseous mixture of ethylene, sulfur dioxide and carbon monoxide by means of Co-60 gamma rays or an electron beam, at a temperature of about 10--50 C, and at a pressure of about 140 to 680 atmospheres, to initiate polymerization.
