    • 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.
    • 目的:提供共轭二烯的橡胶改性聚合物的连续制造方法,以减少能量和二氧化碳,因为不需要溶剂去除方法作为使用蒸馏或水的汽提功能,并且不通过汽提功能通过直接蒸馏 溶剂或水。 构成:橡胶改性聚合物的连续制造方法包括在溶剂存在下,在第一反应器中使共轭二烯系单体聚合而制造橡胶溶液的工序; 通过将苯乙烯基单体与橡胶溶液接触来除去溶剂的步骤; 以及通过在第二反应器中将苯乙烯类单体进入橡胶溶液进行聚合的步骤。 共轭二烯类单体是丁二烯,异戊二烯或其组合。
