Abstract (en)
[origin: WO2009047066A1] The invention relates to compositions containing (A) at least one polymer organosilicon compound, formed from units of formula (I): Ra(R1O)bR2cSiO(4-a-b-c)/2, wherein the radicals and indices have the meanings cited in claim 1, with the proviso that the sum is a+b+c =3, in at least 50 % of all of the units of formulae (I), and the sum a+b+c is equal to 2, the organosilicon compound comprises between 150 to 1500 units of formula (I), and in at least 10 units of the organosilicon compound, c is different from 0. The invention also relates to a method for producing said above-mentioned compositions and to the use thereof as an anti-foaming agent.
