Solvent-free diene rubber solution useful for continuous production of styrene-butadiene rubber, polybutadiene, polyisoprene prepared with insertion of an anionic initiator without sticking of large aggregates to the reactor wall

摘要

Solvent-free diene rubber solutions prepared continuously in a spray tower reactor with an inner wall by polymerization of monomers with insertion of an anionic initiator, and deposition of the diene rubber particles on the reactor inner wall without repulsion by this wall are new. An Independent claim is included for an apparatus for preparing the solvent free solutions comprising a spray tower reactor, a wall and a second wall (1b) with openings arranged so that an inner space is formed between the reactor inner wall and the second wall (1b).
