METHOD OF PREPARING RUBBER-LIKE COPOLYMERS |
| 摘要 |
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 û trialkylaluminum-based complex û 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
