THE INFLUENCE OF INERT COMPONENT COMPOSITION ON THE POROUS STRUCTURE OF GLYCIDYL METHACRYLATE ETHYLENE-GLYCOL DIMETHACRYLATE COPOLYMERS

The influence of the content of inert component in monomer phase on th e parameters of porous structure (specific pore volume, V(S), specific surface area, S(S), total porosity, P, pore size distribution and por e diameter d(p)) of the copolymers of glycidyl methacrylate, GMA, and ethylene glycol dimethacrylate, EGDMA, obtained by suspension polymeri zation has been studied. The content of standard inert component (cycl ohexanol/dodecanol) was changed by substituting dodecanol with one of the aliphatic alcohols with 4, 8, 10, 14 or 16 C-atoms and by varying the ratio of aliphatic alcohol in inert component. The results obtaine d showed that it was possible by changing type and ratio of aliphatic alcohol in inert component to influence the parameters of pore structu re of poly(GMA-co-EGDMA) copolymers significantly and that by using te tradecanol or hexadecanol it was possible to obtain these copolymers w ith pore diameters larger than 200 nm.
