Abstract
Compositions which comprise aminofunctional polyorganosiloxanes and additionally polyorganosiloxanes are described which can be prepared by reacting polysiloxanes with Si—H bonds (H-siloxanes) and specific compounds with carbon—carbon multiple bonds. The last-mentioned compounds comprise acrylate units. The compositions are suitable for the treatment of fabrics, to which advantageous properties are hereby imparted.
Claims14
A composition comprising components A and B and/or a product which is formed by the chemical reaction between component A and component B,
- where component A is a polyorganosiloxane which comprises one or more amino groups and where
- component B is a polyorganosiloxane obtained by reacting an unsaturated compound of the formula (I) or of the formula (II)
- or a mixture of compounds of the formula (I) and of the formula (II) with a polysiloxane of the formula (III)
- or a mixture of the polysiloxanes of formula (III) in quantitative ratios such that the sum of the number of Si—H groups in the polysiloxanes of the formula (III) used is essentially just as great as the sum of the number of alkenyl carbon—carbon double bonds and the number of carbon—carbon triple bonds in the compounds of the formula (I) and (II) used,
- where
- R1 is hydrogen or CH3,
- all of the radicals R present, independently of one another, are hydrogen or an alkyl radical having 1 to 4 carbon atoms, but where at least 2 of all of the radicals R present are hydrogen and where two radicals R bonded to the same silicon atom are not hydrogen at the same time,
- where
- m is a number from 10 to 50,
- n is a number from 0 to 20,
- where in each unit
- one of the radicals R7 and R8 is hydrogen and the other is hydrogen or a methyl group.
An aqueous dispersion comprising
- (i) components A and B and/or a product which is formed by the chemical reaction between component A and component B,
- (ii) component C and
- (iii) component D
- where component A is a polyorganosiloxane which comprises one or more amino groups and where
- component B is a polyorganosiloxane obtained by reacting an unsaturated compound of the formula (I) or of the formula (II)
- or a mixture of compounds of the formula (I) and of the formula (II) with a polysiloxane of the formula (III)
- or a mixture of the polysiloxanes of formula (III) in quantitative ratios such that the sum of the number of Si—H groups in the polysiloxanes of the formula (III) used is essentially just as great as the sum of the number of alkenyl carbon—carbon double bonds and the number of carbon—carbon triple bonds in the compounds of the formula (I) and (II) used,
- where
- R1 is hydrogen or CH3,
- all of the radicals R present, independently of one another, are hydrogen or an alkyl radical having 1 to 4 carbon atoms, but where at least 2 of all of the radicals R present are hydrogen and where two radicals R bonded to the same silicon atom are not hydrogen at the same time,
- where
- m is a number from 10 to 50,
- n is a number from 0 to 20,
- where in each unit
- one of the radicals R7 and R8 is hydrogen and the other is hydrogen or a methyl group,
- and where component C is water and component D is an auxiliary selected from the group consisting of one or more dispersants, polyvinyl alcohol, guar meal and a mixture of one or more dispersants and/or polyvinyl alcohol and/or guar meal.
