Abstract: Free-radical polymerization of N-vinylcaprolactam (VCL) in the presence of chain-transfer agents has been studied to obtain polyvinylcaprolactam possessing a predetermined relative molecular mass. Allyl compounds have been used as chain-transfer agents. Free-radical polymerization kinetics of VCL in the presence of allylbenzene and allylcaprolactam has been investigated as well as free-radical polymerization of VCL in isopropyl alcohol solution. The effect of reaction mixture composition on the rate and degree of polymerization has been studied, too. Possibility of synthesis of vinylcaprolactam oligomers with terminal hydroxyl groups has been demonstrated. Influence of a series of substituents at allylic compounds on kinetics of chain transfer has been investigated using quantum-chemical methods.
