Величину молекул рного веса можно регулировать добавлением активных переносчиков цепи (меркаптанов, четыреххлористого углерода, замещенных бензолов и др.), добавл емых в количестве 0,01 - 5% от веса мономеров.Copolymerization initiators can be acyl peroxide, ketone peroxide, alkyl, hydroperoxide, azo compounds, redox systems. The reaction temperature is 40-160 ° C, preferably 90-120 ° C, the reaction time is 3-60 hours depending on the structure of the monomers, the nature of the initiator, the reaction conditions. The molecular weight can be adjusted by adding active chain carriers (mercaptans, carbon tetrachloride, substituted benzenes, etc.), added in an amount of 0.01-5% by weight of the monomers.
