The characteristics of two types of porous polymers: poly(methyl methacrylate) and copolymers of methyl methacrylate and acrylamide were investigated in this study. Poly(methyl methacrylate) was synthesized in suspension, using ethylene glycol dimethacrylate as the cross-linking agent, poly(vinyl pyrrolidone) as the protective colloid, and benzoyl peroxide as the initiator. The synthesis of poly(methyl methacrylate-co-acrylamide) was initiated in emulsion in the presence of dioctyl sulfosuccinate sodium salt, followed by a sol-gel process, and completely reacted to the solid state. Potassium persulfate was used as the initiator, and tetramethylol glycoluril as the cross-linking agent. Both types of syntheses were carried out in the presence of ethyl acetate. The porosity, specific surface and distribution of the pore sizes of the obtained polymers were determined by mercury porosimetry. The polymers were used as inert carriers for the immobilization of enzymes and whole cells of Saccha...romyces cerevisiae yeast.
U ovom radu su ispitivane karakteristike dve vrste poroznih polimera: poli(metilmetakrilata) i kopolimera metilmetakrilata i akrilamida. Poli(metilmetakrilat) je sintetisan u suspenziji pri čemu je etilenglikol dimetakrilat iskorišćen kao umreživač, poli(vinilpirolidon) kao zaštitni koloid a benzoil peroksid kao inicijator. Sinteza poli(metilmetakrilat-co-akrilamida) je započeta u emulziji u prisustvu natrijum dioktil sulfosukcinata, nastavljena sol-gel procesom i završila u čvrstom stanju. Kao inicijator je korišćen kalijum persulfat, a tetrametilol glikoluril kao umreživač. Obe vrste sinteze su vođene u prisustvu etil acetata. Dobijenim polimerima je određena poroznost, specifična površina i raspodela veličina pora pomoću živine porozimetrije. Iskorišćeni su kao inertni nosači za /mobilizaciju enzima i celih ćelija kvasca Saccharomyces cerevisiae.
