• porous copolymer
• modified silica filler
• adsorption
• solvent resistance

Effect of the silica filler with varied concentration of surface trimethylsilyl and silicon hydride groups on porosity and solvent resistance of divinylbenzene-styrene (DVB-St) and divinylbenzene-di(methacryloyloxymethyl)naphthalene (DVB-DMN) copolymers was studied by adsorption of p-chloroaniline. Filling with silica was shown to increase considerably solvent resistance of DVB-St copolymer, and the filler surface chemistry was found to affect essentially its porosity. Introducing of modified silicas may both increase and decrease solvent resistance of DVB-DMN copolymer, and overall functionalization of filler surface with trimethylsilyl or trimethylsilyl (20%) and silicon hydride (80%) groups have maximum effect on porosity of this copolymer.
