摘要：
Highly cross-linked porous copolymers of 1-vinyl-2-pyrrolidone with divinylbenzene were obtained in the form of microspheres by the free-radical cross-linking copolymerization. The porous structure of the copolymers was created by the use of adequate diluents and stabilizers. The main parameters of the porous structure were determined by nitrogen adsorption/desorption method and positronium annihilation lifetime spectroscopy. It was shown that the determined parameters strongly depend on the chosen approach.
