摘要：

Branched copolymers are synthesized via the crosslinking free-radical copolymerization of N-vinyl-2-pyrrolidone and dimethacrylates of various structures that is conducted in the presence of the chain-transfer agent 1-decanethiol. The kinetics of this process and the composition of the products are studied by IR spectroscopy, and the content of pendant C=C bonds is estimated. Correlations between the content of dimethacrylate monomer units in the copolymer and the rate of discoloration of a photochromic probe (6-nitrospiropyran) incorporated into the product are established.
