Abstract
An organo(poly)siloxane (A) consists of units of general formula (I) RSiO, where R is selected from the radicals R, —OR, R, Rand Q, wherein Rdenotes a monovalent substituted or unsubstituted hydrocarbon radical having 1 to 18 carbon atoms, Rdenotes a hydrogen atom or a monovalent substituted or unsubstituted hydrocarbon radical having 1 to 6 carbon atoms, Rdenotes a monovalent aliphatic unsaturated hydrocarbon radical having 2 to 18 carbon atoms, Rdenotes a monovalent thiol-functionalized hydrocarbon radical, Q is a nitrogen functional group of formula (II) —CRR—NRR, where Rand Reach independently denote hydrogen or a substituted or unsubstituted hydrocarbon radical, and Rand Reach independently denote hydrogen or the methyl radical. The organo(poly)siloxane (A) contains per molecule at least one unit of general formula (III) Q-Si(OR)O, at least 1 aliphatically unsaturated radical R, and at least 2 thiol-functionalized groups R.
