摘要:

Vinyltoluene and divinylbenzene were copolymerized in suspension to obtain copolymers with different cross-linking degrees. The copolymer beads were characterized by specific density measurements and their equilibrium swelling in various solvents was investigated. The average molecular weights between cross-links were calculated based on swelling and glass transition temperature data.
