METHOD OF OBTAINING BORATED 1,2-POLYBUTADIENES Russian patent published in 2014 - IPC C08C19/26 C08C19/38 C08C19/00 C08F8/42 

FIELD: chemistry.

SUBSTANCE: claimed is a method of obtaining borated 1,2-polybutadienes, consisting in the interaction of a polymer with a borating agent, characterised by the fact that before the stage of borating aluminisation and hydroxylation of 1,2-polybutadiene are carried out, where as an aluminising agent used is a mixture of diisobutylaluminium chloride in the presence of (i-OPr)₄Ti with a molar ratio of 1,2-polybutadiene:diisobutylaluminium chloride=1:0.2-4, 1,2-polybutadiene:(i-OPr)₄Ti=1:0.01-0.02 at a temperature of 10-55°C for 12-26 h, hydroxylation of the aluminium derivative of 1,2-polybutadiene is carried out by the action of a hydroxylating agent, which is represented by air oxygen, by hydroxylation of the reaction mass at room temperature for 7-20 h, after which borating is carried out by means of the borating agent, consisting of boric acid and a sodium hydroxide solution, with a molar ratio hydroxylated 1,2-polybutadiene:boric acid 1:0.2-1.3, boric acid:sodium hydroxide 1:0.5-4.2 at room temperature for 0.5-4 h.

EFFECT: reduction of energy consumption and elimination of toxic reagents from the process of synthesis.
