MODIFIER, METHOD OF OBTAINING MODIFIED POLYMER OF CONJUGATED DIENE WITH APPLICATION OF MODIFIER AND MODIFIED POLYMER OF CONJUGATED DIENE Russian patent published in 2015 - IPC C08C19/25 C08F36/04 C08L9/00 C08L9/06 C08L15/00 C08K3/04 C08K3/36 B60C1/00 

FIELD: chemistry.

SUBSTANCE: invention relates to a modifier, a method of obtaining a modified polymer and the modified polymer of a conjugated diene. The modifier for the polymer of the conjugated diene is obtained as a result of the complete condensation for a silicon-containing compound, which has a protected primary amino group and hydrolysable groups. The method of obtaining the modified polymer based on the conjugated diene includes a stage of modification and stage of the protection withdrawal. The tage of the protection is carried out after the completion of modification, and the used polymer based on the conjugated diene is preferably such that 10% of its polymer chains possess live and pseudolive properties.

EFFECT: modified polymer based on the conjugated diene is characterised by an excellent ability of small heat release and resistance to abrasion, which is used in a caoutchouc composition for the pneumatic tread.
