Porous copolymers of 1-vinyl-2-pyrrolidone (VP) with 1,4-di(methacryloyloxymethyl) naphthalene (DMN) have been synthesized by suspension polymerization in the presence of inert diluent. They have different specific surface area and contain various amount of strongly polar pyrrolidone groups. Their sorptive properties have been studied using solution of p-chlorophenol. It was found that adsorption strongly depends on the copolymer polarity. Polymeric sorbents were characterized using elemental analysis, ATR-FTIR, thermogravimetry, differential scanning calorimetry, inverse gas chromatography and their porous structure was determined by low-temperature nitrogen adsorption–desorption method.
