Styrene-acrylic emulsion polymerization conditions for research Abstract The way the use of emulsion polymerization, by use of OS,OP-10 as the emulsifiers. Synthesis of a functional monomer containing acrylic styrene / butyl acrylate emulsion copolymerization. The influence of the amount ,and the ratio of emulsifiers ,temperature,the amount of initiator on the preparation process were discussed.It was found that the lowest cohesion emulsion and the plymerization conversion rate of the highest, when the amount of emulsifiers was 4%, OS∶OP-10 was 3∶1,reaction temperature was 80-85℃, the amount of initiator was 0.5%.
