Abstract Suspension macroporous copolymers containing methyl methacrylate (MMA), butyl acrylate (BA) and vinyl acetate (VA) crosslinked with multifunctional copolymers – trimethylolpropane trimethacrylate (TMPMA) or trimethylolpropane triacrylate (TMPA) – were synthesized and characterized. The copolymers were subjected to aminolysis by ethylenediamine in order to obtain reactive carriers with amino functionalities. The concentration of amino functionalities in the carriers was controlled by modification conditions and the type of the copolymer. In the case of TMPMA homopolymer and copolymers containing MMA, the modification took place mostly on the pore surface. A decrease of pore diameter was observed. The effect was governed by the rigidity of the trimethacrylate structure. In the case of more the flexible TMPA network and copolymers having BA and VA units, the modification with ethylenediamine appeared in the entire volume of the network. As a consequence, the carrier network expanded. For the same cases the modification of the copolymer (TMPA/BA/VA) resulted in the formation of hydrogels which swelling properties were pH‐controlled.
