PACS numbers: 61.41.+e, 78.30.Jw, 81.05.Rm, 81.07.Nb, 81.16.Fg, 81.20.Fw, 82.35.Np

Comparative investigation of matrix polymerization of divinylbenzene in silica mesoporous molecular sieves of SBA-15 and KIT-6 types is carried out. Influence of spatial structure of initial matrix, pore filling degree by an initial monomer, medium, temperature and time of polymerization as well as method of silica removal on the structure and porous properties of polymeric materials is investigated. As demonstrated, the surplus mesopore filling by monomer (1–1.5), polymerization in vacuum and alkaline method of matrix removal are preferable. Method of IR-spectroscopy allows estimating of initial monomer conversion degree by the relative change in intensity of vinyl-group vibrations.
