FIELD: polymer production. SUBSTANCE: in the production of oil and gasoline- resistant elastomers, copolymerization of epichlorohydrin and ethylene oxide is continuously carried out in inert organic solvent at heating in presence of catalyst Ц trialkylaluminum-based complex Ц in two in series connected reactors, the second one being additionally supplied by ethylene oxide in amount 20-50% based on the weight of this reactant introduced into the first reactor. Concentration of copolymer in solvent is maintained constant in the two reactors. EFFECT: enhanced process efficiency. 3 tbl
