Preparation of Porous Copolymer Beads of p-Vinylphenol-Divinylbenzene and their Properties as High-Performance Liquid Chromatographic Packings

Abstract

Porous copolymer beads of p-vinylphenyl acetate (p-VPOAc) and divinylbenzene (DVB) were prepared by suspension copolymerization in the presence of isooctane and 2-ethyl hexyl alcohol mixture as diluent. Porous copolymer beads of p-vinylphenol (p-VP) and DVB were prepared by hydrolysis of the above copolymer beads and then were nitrated. Their structures were examined by infrared spectroscopy. These porous copolymer beads had good performance and separation characteristics as high-performance liquid chromatographic packings for various organic compounds.
