CONTINUOUS PROCESS FOR PREPARING RUBBER-MODIFIED STYRENE POLYMER FROM CONJUGATED DIENE

摘要

PURPOSE: A continuously manufacturing method of rubber-modified polymer from conjugated diene is provided to reduce energy and CO2 because of not requiring solvent removal process as a stripping function using distillation or water, and not having bale formation through the stripping function by direct distillation of solvent or water. CONSTITUTION: A continuously manufacturing method of rubber-modified polymer comprises a step of manufacturing rubber solution by polymerizing a conjugated diene based-monomer in a first reactor under the presence of solvent; a step of removing solvent by contacting styrene-based monomer to the rubber solution; and a step of conducting polymerization by putting the styrene-based monomer into the rubber solution in a second reactor. The conjugated diene-based monomer is a butadiene, isoprene, or combinations thereof.
