MACROPOROUS COPOLYMER METHYLMETHACRYLATE AND ACRYLAMIDE, PROCEDURE OF SYNTHESIS AND USAGE LIKE SUPPORT OF MICROORGANISMS AND ENZYMES

摘要

Presented invention belongs to the field of polymer products and refers to the new product - macroporous copolymer methylmethacrylate and acrylamides with free volume of open pores from 50 to 90%, procedure for obtaining thereof, as well as its application as the carrier on the base of copolymers. Synthesis starts with prepolymerization in emulsion, continuation of the copolymerization with sol-gel procedure up to the formation of solid block, if needed and in the moulds of required form. At the end networking of methyl derivatives of melamine or glycolurile. Macroporous copolymer of methylmethacrylate and acrylamide is the subject of great interest, for the fact that the materials of different purposes are obtained. If these have open pores, it can be used as starting substances for obtaining different ionexchange resins, as absorbers, inert carriers of catalyst particles, enzymes or whole cell of microorganisms. If in the procedure of preparation thereof, steps are taken so as that the pores remain closed a foamlike material will be obtained, and this can be used as a light building structure or as a good insulating material. The obtained product is characterised by the stable structure.;Predloeni pronalazak je iz oblasti polimernih proizvoda i odnosi se na novi proizvod - makroporozni kopolimer metilmetakrilata i akrilamida sa slobodnom zapreminom otvorenih pora od 50 do 90%, postupak za njegovo dobijanje, kao i primena kao nosaa na bazi kopolimera. Sinteza poinje predpolimerizacijom u emulziji, nastavak kopolimerizacije sol-gel procesom do dobijanja vrstog bloka, po potrebi i u kalupima zahtevanog oblika. Na kraju se izvodi umreavanje metilol derivatima melamina ili glikolurila. Makroporozni kopolimer metilmetakrilata i akrilamida je predmet velikog interesovanja, jer se odbijaju materijali razliite namene. Ako imaju otvorene pore mogu se koristiti kao polazne supstance za dobijanje razliitih jonoizmenjivakih smola, kao adsorbenti, inertni nosai estica katalizatora, enzima ili celih elija mikroorganizama. Ako se u postupku dobijanja proces vodi tako da pore ostanu zatvorene dobie se penasti materijal, koji se moe iskoristiti kao laki konstrukcioni materijal ili kao dobar izolator. Dobijeni proizvod se odlikuje stabilnom strukturom.[Presented invention belongs to the field of polymer products and refers to the new product - macroporous copolymer methylmethacrylate and acrylamides with free volume of open pores from 50 to 90%, procedure for obtaining thereof, as well as its application as the carrier on the base of copolymers.
