Abstract
1. A method of regulation of the porous structure of polysiloxane hydride xerogels was described. Samples of polysiloxane hydride xerogels with various porous structures were obtained. 2. The porous structure of polysiloxane hydride xerogels is determined chiefly by the surface tension of the intermicellar liquid and by the nature of its interaction with the surface of the lyogel. 3. An analysis of the porous structure of typical samples of polysiloxane hydride xerogels was given on the basis of the sorption isotherms of benzene. 4. The porous structure of polysiloxane hydride xerogels is formed by globules in contact, and its parameters are determined by the average diameter of the globules and the average coordination number. The volumes of the different varieties of pores, the specific surface of the transitional pores, and the constants of the equation of the theory of volume filling of micropores, which are parameters of the microporous structure, characterize the porous structure of polysiloxane hydride xerogels.
