Copolymerization of 1,3-butadiene and styrene in the presence of an initiating system based on n-butyllithium, amine-containing modifier, and 2,2'-ditetrahydrofurylpropane

Abstract

The kinetic parameters of copolymerization of 1,3-butadiene and styrene in hexane under the action of a ternary initiating system consisting of n-butyllithium, amine-containing alkali and alkaline earth metal alcoholates, and 2,2'-ditetrahydrofurylpropane were studied. The molecular mass characteristics and microstructure of the synthesized copolymer samples were examined. Physicomechanical tests of specimens of butadiene–styrene rubber prepared from solution and of vulcanized specimens based on them were performed.
