Abstract
FIELD: technology of high molecular weight compounds, namely production of stereoregular polydienes with the help of catalytic systems of Ziegler-Natte type. SUBSTANCE: method for production of cis-1,4-polybutadiene and cis-1,4-copolymer of butadiene and isoprene is carried out by polymerization and copolymerization of corresponding monomers. The process takes place in aromatic solvent, catalyst on the base of compounds of rare-earth elements being used. At the end of polymerization quinoline ether is added, its quantity being 0.01-1.0 mass %. EFFECT: decreased plasticity of desired products.
