摘要：The effects of initiator, modifier, electrolyte, and emulsifier on emulsion polymerization of styrene butadiene rubber were investigated. The results showed that the conversion could reach up to 70% within 12 hour with the same properties as conversion 62% without changing the kinds and specification by using the adjusted recipe: the amount of initiator Was 10%, the mass ratio of initial amount to addition amount of molecular weight regulator was 100/20, addition time was at polymerization beginning 2 hour, the initial amount of electrolyte was 110%-115%, the total amount of emulsifier was 110%, the addition amount of emulsifier was 10% and adding time was at polymerization beginning 2 hour. the raw and vulcanizate properties of rubber crumb high monomer conversion of 70% by adjusting recipe were satisfied to meet the requirements of the superior product standard of styrene butadiene rubber.
