ADDITIVE AND METHOD OF TERMINATING POLYMERISATION AND/OR REDUCING VISCOSITY OF POLYMER SOLUTION Russian patent published in 2014 - IPC C08F6/00 C08F6/06 C08C2/00 C08L101/00 C08J3/02 

FIELD: chemistry.

SUBSTANCE: disclosed is an additive for reducing viscosity of a polymer solution, which includes: A. carboxylic acid, B. an alcohol, C. a salt selected from a group consisting of an alkali metal salt, an alkali-earth metal salt, an ammonium salt and a mixture thereof, and E. optionally water. Also disclosed is a method of reducing viscosity of a polymer solution, which includes adding the additive and using the additive to reduce viscosity of the polymer solution.

EFFECT: disclosed additive considerably reduces viscosity of a polymer solution, can effectively terminate the ends of living polymer chains and destroy catalytic active centres.
