CONTINUOUS PROCESS FOR PREPARING RUBBER-MODIFIED AROMATIC VINYL POLYMER FROM CONJUGATED DIENE

摘要

PURPOSE: A method for consecutively manufacturing rubber degeneration aromatic vinyl polymers from a conjugated diene is provided to variously control molecular weight or physical property according to required grade. CONSTITUTION: A method for consecutively manufacturing rubber degeneration aromatic vinyl polymers from a conjugated diene comprises the following steps: a step of manufacturing rubber solution(r) by polymerizing monomer including conjugation diene in a first reactor(10); a step of discharging the monomer solution used for polymerization of the rubber degeneration aromatic vinyl polymer with the rubber solution when transferring the rubber solution to a second reactor(20) which the rubber degeneration aromatic vinyl polymer is polymerized; and a step of polymerizing a mixing solution of the rubber solution and the monomer solution in the second reactor.
