Patent ID: 8623984

Claim:
A composition comprising compounds of formula (I) where the indices a are each, independently of one another, from 0 to 500, the indices b are each, independently of one another, from 0 to 60, the indices c are each, independently of one another, from 0 to 10, the indices d are each, independently of one another, from 0 to 10, with the proviso that Σc+Σd is greater than or equal to 1 per molecule of formula (I) and that the average number Σd of T units and the average number Σc of Q units per molecule are in each case not greater than 50, the average number Σa of D units per molecule is not greater than 2000 and the average number Σb of siloxy units bearing R4 per molecule is not greater than 100, the radicals R are each at least one radical from the group consisting of linear, cyclic or branched, aliphatic or aromatic, saturated or unsaturated hydrocarbon radicals having from 1 to 20 carbon atoms, the radicals R5 are each, independently of one another, R4, —OR8 or R, the radicals R4 are each, independently of one another, —OR8 or an organic radical which is not R, the radicals R7 can each be R, R4, —OR8 and/or a heteroatom-substituted, functional, organic, saturated or unsaturated radical selected from the group consisting of alkyl, chloroalkyl, chloroaryl, fluoroalkyl, cyanoalkyl, acryloxyaryl, acryloxyalkyl, methacryloxyalkyl, methacryloxypropyl and vinyl radicals, the radicals R8 are each, independently of one another, hydrogen or an alkyl radical having from 1 to 10 carbon atoms, with the proviso that at least one substituent from among R4, R5 and R7 is not R and at least one compound of formula (I) in which at least one of the radicals R4, R5 and R7 is a radical —OR8 is present and, averaged over all compounds of the formula (I) present in the composition, not more than 20 mol % of the radicals R4, R5 and R7 are —OR8.
