Investigation of porous structure polymeric materials based on 1‐vinyl‐2‐pyrrolidone

Investigation of porous structure polymeric materials based on 1‐vinyl‐2‐pyrrolidone 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. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Polymers for Advanced Technologies Wiley

Abstract

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.
