摘要：

The effect of the diluent solvating power on the porosity and swelling properties of styrene-divinylbenzene copolymers was investigated. A mechanism for the swelling of macroporous copolymers in good and poor solvent was proposed. The porous structures were classified according to kinetic data of a poor solvent sorption. When the diluent-copolymer affinity was reduced, the fixed pore volume increased, but the nuclei swelling and the elasticity of internuclear chains diminished.
