摘要: A Monte Carlo simulation model for the semibatch emulsion polymerization of acrylate monomers was developed. The accounts complex kinetics (presence chain-end and midchain radicals), compartmentalization systems development entire molecular weight distribution (MWD) as well branching density. It found that MWD produced in process bimodal (a sharp extremely high Mw peak a broad lower mode), radicals were predominant during polymerization, most branches short by backbiting mechanism. Interestingly, bimodality could be avoided under certain experimental conditions (those who led to decrease particles with more than two but this did not prevent formation polymer chains weights above 107 g/mol (which are typically insoluble). also shows importance presence m...
