Synthesis and characterization of crosslinked copolymers based on syrene, divinylbenzene and methyl methacrylate with magnetic properties

In this work, copolymers based on styrene (STY), divinylbenzene (DVB) and methyl methacrylate (MMA) with magnetic properties were synthesized using the suspension polymerization technique. The copolymers were characterized according to morphology, iron content incorporated, bulk density, particle size distribution and magnetic properties. The effect of MMA content on the characteristics of polymeric particles was investigated. Generally, copolymers without MMA presented the biggest iron content incorporated and the best morphologic control. When the temperature was decreased from 80 ºC to 70 ºC and the stirring speed was reduced from 480 rpm to 360 rpm the iron content in the polymeric particles increased.
