Composition control of copolymer in semibatch emulsion copolymerization. II. MMA/styrene/BMA three-component system

摘要

In this study, polymers of the MMA/Styrene/BMA three-component system were synthesized through either soapless semibatch emulsion copolymerization or soapless batch emulsion copolymerization technique. The optimal monomer feed flow rate was determined from the interphase partition laws, monomer reactivity ratios, and three or four times of iterative experimental procedures through semibatch emulsion copolymerization. As a result, the instantaneous composition of polymers could also be effectively controlled to get the desired final products. (C) 2000 John Wiley & Sons, Inc. [References: 22]
