Abstract
525,335. Plasticizing rubber. COOPER, L. Feb. 17, 1939, No. 5374. Drawings to Specification. [Class 70] Indiarubber is plasticized by the action of air, or other gas containing free oxygen, at elevated temperatures and pressure, as for example at a temperature of 212‹-400‹F. and a pressure of 200-300 lb. per sq. inch for ¢-6 hours. The rubber may be heated until it approaches the liquid state before being submitted to the gas.
