摘要：
Composition comprising acrylamido-functional siloxanes that are derived from a) a reaction of a component A, which is an aminoalkyl-functionalized silicon compound, chosen from (i) an aminoalkyl-functional alkoxysilane of the formula I or a mixture of aminoalkyl alkoxysilanes - functional of the formula I, in each case in the presence of a defined amount of water, or (ii) a hydroxysis or condensation product of at least one amino-alkyl-functional alkoxysilane of the formula I, or (iii) a mixture which it comprises at least one aminoalkyl functional alkoxysilane of the formula I and a hydrolysis and / or condensation product of at least one aminoalkyl functional alkoxysilane of the formula I, wherein the aminoalkyl functional alkoxysilane corresponds to the formula I (R1O) 3-ab (R2) aSi (B) 1 + b (I), and group B of formula I independently corresponds to a group of formula II - (CH2) c [(NH) (CH2) d] e [(NH)] (CH2) f] gNH (2-h) R3 h (II) in formula I with R1, independently nte, an alkyl group with 1 to 8 C atoms, linear, branched or cyclic, R2 is, independently, an alkyl group with 1 to 8 C atoms, linear, branched or cyclic, and in formula II with R3, independently , an alkyl, aryl or alkylaryl group having 1 to 8 C atoms, linear, branched or cyclic, and in formula I a, independently, is equal to 0 or 1, b, independently, is equal to 0 or 1, in formula II, c, independently, is chosen from 1, 2, 3, 4, 5 and 6, d, independently, is chosen from 1, 2, 3, 4, 5 and 6, and, independently, is chosen from 0 , 1, 2, 3, 4, 5 and 6, f, independently, is chosen from 1, 2, 3, 4, 5 and 6, g, independently, is chosen from 0, 1, 2, 3, 4, 5 and 6, and h, independently, is 0 or 1, or group B corresponds to formula III - (CH2) j-NH2-p (CH2-CH2-NH2) p (III) with j>； = 1, 2 or 3 and p>； = 0, 1 or 2, preferably p is chosen from 0 and 1, with a component B which is an acrylic acid anhydride and, optionally, in the presence of a diluent, and, optionally, b) separation of at least a porti
