Abstract

Acomparative study regarding the magnetic fields effects during copolymerisation reaction of styrene with 2,3 – epoxypropyl methacrylate using a radical polymerisation in emulsion procedure is presented. The kinetic aspects are correlated with the reaction conditions: various compositions of the reaction mixtures, and the presence of the magnetic field. The obtained copolymers have been characterized by thermal (TG, DSC) methods. It has been established that the magnetic field presence increases the polymerisation rate and conversion, and the obtained copolymers have a higher molecular weight and thermal stability..
