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 formulan is 1, 2, 3 or 4; Rand Rare independently hydrogen (H), Calkyl, C-Ccycloalkyl, C-Caryl, or Rand Rtogether with the carbon atom with which they are bonded form a monocyclic C-Ccarbocyclic ring; Rand Rare independently C-Calkyl, C-Ccycloalkyl, C-Caryl, C-Caryl, once or multiple times substituted with C-Calkyl; R, if n equals 1, is H, C-Calkyl or acyl, selected from a group consisting of the following acyls: -C(=O)-H, -C(=O)-C-Calkyl, -C(=O)-C-Caryl, -C(=O)-O-C-Calkyl and -C(=O)-NH-C-Caryl; R, 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.11 cl, 4 tbl, 21 ex |
