METHOD OF SYNTHESIS OF 1,2-POLYBUTADIENE Russian patent published in 1997 - IPC

Abstract RU 2083598 C1

FIELD: chemical technology. SUBSTANCE: process of butadiene-1,3 polymerization is carried out for two stages. At the first stage n-butyllithium (12-30 mole per 1 t monomer) and modifying addition taken from the group: diethylene glycol dimethyl ether, diethylene glycol divinyl ether, tetramethylethylenediamine, permethylated polyethylenepolyamines, dipiperidineethane (mole ratio to n-butyllithium = 0.1-5.0) were added to charge containing monomer at the parent concentration 10-20 wt.-%. Process is carried out at 20-45 C up to monomer conversion 95%, not less. At the second stage divinylbenzene is added (mole ratio to n-butyllithium = 0.1-0.5), kept for at least 16 min followed by additional addition of butadiene-1,3 as the charge at the same parent concentration of monomer (mass ratio to butadiene-1,3 = 0.8-1.2) and process is carried out at 45-80 C up to conversion 95%, not less. Method is used for synthesis of high-molecular polybutadiene that can be used in rubber industry. EFFECT: improved properties of 1,2-polybutadiene. 1 tbl
