METHOD OF HYDROGENATION OF DIENE POLYMER

摘要

FIELD: chemistry of polymers. SUBSTANCE: present invention describes method of hydrogenation of diene polymer by contacting with titanium hydrogenation catalyst in the presence of hydrogen. Improved method comprises preventing change of color hydrogenated polymer treated with water, peroxide or alcohol in the absence of oxygen and addition of non-phenolic antioxidant to polymer. EFFECT: more efficient hydrogenation method. 8 cl, 4 tbl
