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.

Изобретение относится к технологии высокомолекулярных соединений, а именно к способам получения стереорегулярных полидиенов под влиянием каталитических систем типа Циглера-Натта и может найти применение в нефтехимической промышленности. Предложен способ получения цис-1,4-полибутадиена и цис-1,4-сополимера бутадиена и изопрена полимеризацией и сополимеризацией указанных мономеров в ароматическом растворителе под влиянием катализатора на основе соединений редкоземельных элементов. По окончании процесса полимеризации в полимеризат вводят хиноловый эфир в количестве 0,01 - 1,0 мас.% на мономер. Преимуществом способа является возможность получения цис-1,4-полибутадиена и цис-1,4-сополимера бутадиена и изопрена с пониженной пластичностью и хладотекучестью и высокими физико-механическими свойствами.The invention relates to the technology of macromolecular compounds, and in particular to methods for producing stereoregular polydienes under the influence of Ziegler-Natta type catalytic systems and can find application in the petrochemical industry. A method for producing cis-1,4-polybutadiene and cis-1,4-copolymer of butadiene and isoprene by polymerization and copolymerization of these monomers in an aromatic solvent under the influence of a catalyst based on rare-earth compounds is proposed. At the end of the polymerization process, quinol ether is introduced into the polymerizate in an amount of 0.01 - 1.0 wt.% Per monomer. The advantage of the method is the ability to obtain cis-1,4-polybutadiene and cis-1,4-copolymer of butadiene and isoprene with reduced ductility and cold flow and high physical and mechanical properties.
