Abstract:
1. A reactive organopolysiloxane prepared by hydrolytic condensation, containing on average a) at least two reactive functional groups per molecule, selected from the group consisting of epoxy, isocyanate, anhydride, amino, carboxy, and (meth)acrylate groups, and mixtures thereof, the functional groups SiC-bonded to silicon atoms in the reactive organopolysiloxanes, and b) alkoxy groups, in a concentration of from 1 weight percent to less than 20 weight percent based on the total weight of the reactive organopolysiloxanes, calculated on the basis of methoxy groups, and c) non-reactive optionally substituted hydrocarbon groups Si—C bonded to silicon atoms of the reactive organopolysiloxane, the non-reactive optionally substituted hydrocarbon groups present in a ratio of ≧1.1 and less than 1.5 hydrocarbon groups per atom of Si in the reactive organopolysiloxane, wherein the reactive organopolysiloxane is a non-resinous liquid, linear organopolysiloxane having a viscosity of from 50 cps to 10
