چکیده:
Emulsion polymerization of styrene/Butadiene/Acrylic Acid is simulated using Monte Carlo method. Carboxylic monomers, such as acrylic acid, are widely used in emulsion polymerization. Some important of assumption to run the simulation is: interval I isinished when all of micelles have disappeared, the rate of monomer addition depends only on the nature of the terminal group. The effects of water-soluble monomers, in this
study acrylic acid (AA), in emulsion polymerization w ere studied in styrene/butadiene/acrylic acid. With AA addition in reaction system, duration of interval I increased and this indicate that both micellar and homogenous nucleation were carried out. The most important results in this simulation with Monte Carlo method to achieve tri- and tetra-functional branching and molecular weight distribution. Water-soluble monomers addition in emulsion polymerization has a pronounced affect on the molecular weight distribution due to an increase in the number of polymer particles same as emulsifier effects.
