Structures of copolymers of styrene and divinylbenzene (50% crosslinking degree) prepared in suspension polymerization in the presence of mixtures of nonsol (heptane or decane) and sol (toluene or tetralin) diluents were investigated. The studies showed that the diluents enriched with nonsol solvent
AbaWaet-Hollow geluhu beads of styrentiivinylbenzene copolymer have been prepared only by controlling the Polymerization temperature and the amount of initiator. A mechanism for the formation of hollow beads is described.
## Abstract Suspension copolymerization of styrene and divinylbenzene (DVB) was carried out using benzoyl peroxide as initiator and magnesium hydroxide as suspending agent in water at 80°C under nitrogen atmosphere to produce styrene–DVB copolymer beads. These beads were characterized by infrared s
