Reactions of Transformation of Polyacrylamide Obtained by Polymerization in Inverse Suspension

Some results on the polymerization of acrylamide in heterogeneous systems are presented. The first part presents the polymerization of acrylamide in inverse suspension; the steps of the reaction and the part played by each factor that influences the advancement of the reaction are discussed. Some aspects whose elucidation was required throughout the investigation are presented, together with a hypothesis and the experimental results obtained. The second part presents reactions of the modifications achieved with the polymers obtained in inverse suspension and the properties of modified polymers. The final section reports some attempts to entrap some enzymes in polyacrylamide gel. The results of entrapment by copolymerization of acrylamide with methylenebisacrylamide in a homogeneous system are presented comparatively with those yielded by the same reaction in a heterogeneous system.
