N2 - Monomer partitioning in emulsion copolymn. plays a key role in detg. compn. drift and polymn. rates. The combination of recently developed thermodn. based on monomer partitioning relationships with mass balance equations makes predictions of monomer partitioning in emulsion copolymns. possible in terms of monomer mole fractions and monomer concns. in the particle and aq. phases. Using this approach, the effects of monomer to water ratios and polymer vols. on the monomer mole fraction within the polymer particle phase in a nonpolymg. system at thermodn. equil. can be detd. Comparison of these monomer partitioning predictions with expts. for the monomer system Me acrylate-vinyl acetate shows good agreement. Furthermore, compn. drift occurring in a polymg. system as a function of conversion can be predicted if the assumption is made that equil. is maintained during reaction. Comparison of predictions with exptl. results for emulsion copolymns. of the monomer systems Me acrylate-vinyl acetate and Me acrylate-indene shows good agreement
