<p>PURPOSE: A manufacturing method of rubber polymer latex capable of enhancing polymerization stability and conversion rate and a manufacturing method of abs based graft copolymer are provided to accomplish high conversion rate in short time. CONSTITUTION: A manufacturing method of rubber polymer latex capable of enhancing polymerization stability and conversion rate comprises the following steps: performing polymerization by putting 50-85 wt% of conjugate diene based monomer among 100wt%; and performing polymerization by putting 0.05-1 parts by weight of reactive surfactant based on 100 parts by weight of the monomer, 15-50 wt% of conjugated diene monomer when the polymerization conversion rate is 30-70%. The polymerizing step includes 2 parts by weight or less of emulsifier based on 100 parts by weight of monomers.</p> |
