Continuous process for the preparation of random conjugated diene/vinyl arene copolymers

摘要

Continuous process carried out in the presence of at least two reactors in series, for the preparation of statistical vinyl arene/conjugated diene copolymers, the vinyl arene content ranging from 15 to 50% by weight, by means of the copolymerization under isothermal conditions in a hydrocarbon solvent, at a temperature ranging from 30 to 120°C, of vinyl arene/conjugated diene monomers, in the presence of at least one initiator and a 2-methoxy ethyl tetra-hydrofuran (THFA-ethyl) modifier.
