STUDIES ON THE POROUS STRUCTURE OF DI(METHACRYLOYLOXYMETHYL)NAPHTHALENE-DIVINYLBENZENE COPOLYMERS BY INVERSE EXCLUSION CHROMATOGRAPHY

Using inverse exclusion chromatography the porous structure of the copolymers of di(methacryloyloxymethyl)naphthalenes and divinylbenzene was investigated. In order to determine the pore size distributions of the copolymers, toluene, alkylphenones, phthalates and polystyrene standards were used as the probes. The measurements proved that the existence of micropores depend on the method of copolymerization. The copolymers obtained by suspension and emulsion methods are more or less microporous, but the copolymer prepared by thermal polymerization in mass does not include micropores in its internal structure.
