Patent ID: 8304568

Claim:
Flowable polyhydroxyamido-containing organopolysiloxanes of the formula A x R 3-x SiO(SiR 2 O) m SiR 3-y A y (I) where A represents a monovalent radical of the formulae —R 1 —N(R 2 )—Z (IIa) or —R 1 —NR 3 —R 4 —N(R 2 )—Z (IIb), Z represents a radical derived from a hydroxy carboxylic acid or lactone thereof, or an oxidized mono- or disaccharide that contains 2 or more hydroxyl groups, R represents a monovalent, optionally halogenated hydrocarbyl radical having 1 to 18 carbon atoms, R 1 represents a divalent organic radical having 1 to 100 carbon atoms which may contain one or more non-adjacent oxygen atoms, R 2 represents a hydrogen atom or a monovalent hydrocarbyl radical having 1 to 18 carbon atoms, R 3 represents a hydrogen atom or Z, R 4 represents a divalent hydrocarbyl radical having 1 to 6 carbon atoms, m is an integer from 1 to 500, x is 0 or 1, y is 0 or 1, with the proviso that the sum x+y is on average 0.4 to 1.8 and thus there are an average of 20 to 90 mol % of the A radicals present as end groups.
