O-IMINO-ISOUREA COMPOUNDS AND POLYMERISABLE COMPOSITIONS THEREOF Russian patent published in 2015 - IPC C07C275/70 C08F4/00 C08F2/02 

FIELD: chemistry.

SUBSTANCE: invention relates to use of O-imino-isourea compounds of general formula (I) and salts thereof as a radical source, particularly as polymerisation initiators. In formula

n is 1, 2, 3 or 4; R₁₀₀ and R₁₀₁ are independently hydrogen (H), C_1-18 alkyl, C₃-C₁₂ cycloalkyl, C₆-C₁₄ aryl, or R₁₀₀ and R₁₀₁ together with the carbon atom with which they are bonded form a monocyclic C₃-C₁₈ carbocyclic ring; R₁₀₂ and R₁₀₃ are independently C₁-C₁₈ alkyl, C₃-C₁₂ cycloalkyl, C₆-C₁₄ aryl, C₆-C₁₄ aryl, once or multiple times substituted with C₁-C₁₈ alkyl; R₁₀₄, if n equals 1, is H, C₁-C₁₈ alkyl or acyl, selected from a group consisting of the following acyls: -C(=O)-H, -C(=O)-C₁-C₁₈alkyl, -C(=O)-C₆-C₁₄aryl, -C(=O)-O-C₁-C₁₈alkyl and -C(=O)-NH-C₆-C₁₄aryl; R₁₀₄, if n is greater than 1, denotes diacyls, triacyls or tetraacyls.

EFFECT: invention relates to novel O-imino-isourea compounds, compositions for radical polymerisation using O-imino-isourea compound, a method of producing an oligomer, a co-oligomer, a polymer or copolymer in free-radical polymerisation conditions and use of O-imino-isourea compounds to produce a coating.
