摘要
Controlled radical polymerization with reversible chain transfer by addition-fragmentation mechanism of NH-unsubstituted 5-vinyltetrazole and its copolymerization with N-vinyl succinimide in the presence of dibenzyltrithiocarbonate was conducted. The polymerization kinetics and molecular weight parameters of the synthesized polymers were studied using NMR spectroscopy and gel permeation chromatography. The chain transfer constants of dibenzyl trithiocarbonate for the homopolymerization of 5-vinyltetrazole and its copolymerization with N-vinyl succinimide were evaluated for different compositions of the monomer mixture. The copolymerization constants of the monomers were determined and the microstructure of the resulting copolymers was described.
