METHOD FOR PRODUCTION OF ETHYLENE/PROPYLENE COPOLYMERS Russian patent published in 2001 - IPC

Abstract RU 2162473 C1

FIELD: polymer production. SUBSTANCE: invention relates to preparation of materials applicable as depressants for fuel and lube oils and as plasticizers in construction and aircraft sealing compositions. High-molecular rubber is heated owing to dissipation therein of mechanical energy and subjected to thermal destruction under intensive shear deformation conditions at shear rate 2500-5000 s-1. Process is carried out continuously. EFFECT: extended copolymer molecular weight range, simplified preparation procedure, and enabled wide-range productivity variation and utilization of substandard starting rubber. 1 tbl, 10 ex
