Abstract:
1. A compound comprising at least two organopolysiloxane units and at least one methylol group of the formula (1) where M1 is an —HCR R L wherein at least 50% of organopolysiloxane units bear unsubstituted hydrocarbyl radicals or Si—O—Si bonds, having the formula (2)  where the units 2a and 2b may be disposed randomly, blocklike, alternatingly or in a mixture thereof, the units 2a and 2b conforming to the formulae (2a) and (2b) where 1 and c represent a whole number of at least 1, R R is hydrogen or a monovalent C R n is a whole number from 1 to 1000, X is an alkylene radical which has 1 to 60 carbon atoms and in which nonadjacent methylene units are optionally replaced by a group —O— or —S—, A is an oxygen atom, a sulfur atom or —NR Z is an oxygen atom, a sulfur atom or —NR Y is a bivalent, optionally fluorine- or chlorine-substituted hydrocarbyl radical which has 1 to 20 carbon atoms bonded to N of the NR D is an alkylene radical which has 1 to 700 carbon atoms, which is optionally substituted by fluorine, chlorine, C Q is a reactive or nonreactive end group attached to the polymer by a covalent bond.
