METHODS OF PRODUCTION OF THE COPOLYMERS FROM NONSATURATED MONOCARBOXYLIC ACID AND THE DERIVATIVE OF THE MONOUNSATURATED CARBOXYLIC ACID AND THE MATERIAL PRODUCED BY THE GIVEN METHODS Russian patent published in 2007 - IPC C08J9/00 C08L33/24 C08F265/04 C08F265/10 

FIELD: chemical industry; methods for production of the copolymers from the nonsaturated monocarboxylic acid and the derivative of the monononsaturated carboxylic acid and the material produced by the given methods.

SUBSTANCE: the invention is pertaining to the bulk polymetric compounds gained by the casting method. The invention presents the versions of the method of production of copolymers from the nonsaturated monocarboxylic acid and the derivative of monounsaturated carboxylic acid by the casting method, at which the polymerization is conducted at the phase of the syrup produced by addition of the polymetric compounds dissolvable in the mixture of the initial monomers. At that as the nonsaturated monocarboxylic acid they use the methacrylic acid, and as the derivative of the monounsaturated carboxylic acid use the metacrylonitrile. The produced material can contain up to 400 mass shares of the parts of the additives in terms of the total mass capable to polymerization groups, which are insoluble in the reaction mixture necessary for production of the material.

EFFECT: the invention ensures production of the copolymers from the nonsaturated monocarboxylic acid and the derivative of the monononsaturated carboxylic acid and the material produced by the given methods.
