Simulation of Heterogeneous: Free Radical Polymerization Reactions
This note is concerned with modeling the radical grafting of styrene-acrylonytrile onto ethylene-propylene ethylydennorbornene copolymer (EP-ENB) initiated by benzoyl peroxide in benzene/n-heptane solution. Indications stemming from previous work on similar reactions [19.1,2,3] suggest that the mechanism might be heterophasic and that polymer segregation might be responsable for a particular decreasing trend observed in the grafting efficiency curve. This possibility is analyzed in detail by a more complete model which takes into account both physical effects related to phase separation and also phase volume changes during the reaction.

- 19.6The integration of the system of ODE was carried out using a variable step and order method based on implicit backward differentiation multistep formulas (adaption of Gear’s subroutine). The minimization algorithm used in the derivation of rate constants provides a suitable combination of the Levenberg-Marquardt and steepest descent methods.Google Scholar
