摘要
Network copolymers of styrene with divinyl sulfide were synthesized in the presence of an agent of free-radical living polymerization, N,N'-bis(vinyloxyethyl)thiuram disulfide. A quick IR spectroscopy test for determining copolymer composition was developed. The reactivity of monomers, the composition of copolymers, and the kinetics of polymerization were studied. The manifestation of the gel effect at higher conversions suggests that the copolymerization proceeds by the living chain mechanism.
