| titleOfInvention | Method of producing butadiene polymers and copolymers of butadiene with styrene |
| abstract | FIELD: chemistry. n SUBSTANCE: invention relates to chemistry of high-molecular compounds, specifically to a method of producing butadiene polymers and copolymers of butadiene with styrene. The polymers are obtained through continuous solution polymerisation. The process is carried out in a hydrocarbon solvent medium in the presence of an organolithium compound and a modifying additive. The modifying additive used is a product of reacting lapramolate of an alkali metal with tetrahydrofurfuryl alcohol, sodium or organolithium compound. The catalyst complex contains an organolithium compound and a modifying additive. The hydrocarbon solvent contains toluene or xylene. After polymerisation of monomers, a blending agent - tetraethoxysilane or silicon tetrachloride is added to the reaction mass. Before separation, oil - softening agent is added to the polymer solution. The method of producing polymers in accordance with the invention allows for obtaining polybutadiene and copolymers of butadiene with styrene with regulated content of 1,2-links in the diene part at high temperature. n EFFECT: easier removal of heat of reaction in polymerisation reactors and reduced expenses on coolant. n 3 cl, 10 ex, 4 tbl |
