FIELD: polymer production. SUBSTANCE: polymers are prepared by copolymerization of corresponding monomers in presence of chain-transfer agent, in particular, cyclopentane substituted by one or several +30°C-alkyls, at temperature from -30 to 30 C. Advantage of alkyl-substituted cyclopentanes reside in their being liquid and therefore easy to process and also because they give terminal alkyl groups with high heat resistance. EFFECT: improved feasibility of process. 11 cl, 1 tbl, 12 ex
