| Abstract: | The copolymer beads of methyl methacrylate （MMA）-styrene （ST） were synthesized by the suspension polymerization. The effects of the amount of initiator, stirring speed, temperature, amount of dispersant, water and the proportion of monomer on suspension polymerization of methacrylate （MMA）-styrene （ST） were researched. The experimental results showed that under the circumstances that the ratio of water to monomer was 6 ： 1, styrene （ST） was 2mL, methyl methacrylate （MMA） was 7.5mL, dispersant （PVA was 0.0025g, SDBS was 0.0045g, calcium phosphate was 0.43g）, initiator benzoyl peroxide （BPO） was 0.33g, stirring speed was 300r/min and reaction temperature was 81℃, the methyl methacrylate-styrene eopolymer was synthesized with appropriate particle size, good transparency and high yield. |
