METHOD OF RUBBER MODIFYING AGENT PRODUCING Russian patent published in 1998 - IPC

FIELD: rubber industry. SUBSTANCE: method involves dispersing a nitrogen-containing polymer an and oxygen-containing compound in water at mass ratio of a nitrogen-containing polymer, water and an oxygen-containing compound = 1:(0.1-10.0):(0.05-0.5) followed by treatment with reaction mass of carrier - silicon dioxide or kaolin, or zeolite, or lignin at mass ratio of nitrogen-containing compound, an oxygen-containing compound and carrier = 1: (0.05-0.5): (1-30) and the obtained product is isolated. Nitrogen-containing compound: polyethyleneimine, or polyhexamethyleneguanidine, or polyethylenepolyamine at polymerization degree 2-10, 2-90 and 2-10, respectively. Oxygen-containing compound: polyethylene glycol or polypropylene glycol or derivative of hydroxybenzene. EFFECT: improved method of producing. 2 tbl
