Summary
The influence of Friedel-Crafts reaction on the properties of poly(styrene-divinylbenzene) porous copolymers was studied. Two porous copolymers containing 0.7 and 0.9 mole fractions of divinylbenzene were used for modification. The aim of the process was to increase the copolymer crosslinking. As a crosslinker, tetrachloromethane in the presence of aluminium chloride was used. Reactions were monitored by FTIR and XRF analyses.
The main result of the modification process is the change of the copolymer porous structure. Modification also has an influence on the chromatographic properties of the copolymers, especially selectivities.
