Use of alkoxysilyl polyorganosiloxanes for treating textiles

Claim 1

A method for preparing an alkoxysilyl functional silicone represented by a formula selected from the group consisting of: and wherein R is an alkyl or an acyl hydrocarbon radical having from one to four carbon atoms, preferably a methyl radical; R i is an alkyl radical of from one to two carbon atoms or a mixture thereof, preferably a methyl radical; R 2 is an alkyl radical having from one to three carbon atoms, mixtures thereof, or an aryl radical selected from the group consisting of phenyl, benzyl and phenylethyl, mixtures thereof, or a mixture of said alkyl and aryl radicals, preferably methyl radical; w is an integer of from 2 to about 20, preferably either 2 or 3; x is an integer of from 0 to 2, preferably either 0 or 1; y is an integer of an average of at least 6, preferably of an average of from 6 to about 1000 and z is an integer of an average of at least 1, preferably of an average of from 1 to about 100, comprising reacting in a first step a silanic hydrogen functional silicone precursor selected from the group consisting of and wherein R 1 , R 2 , y and z have the same meaning as in formulas I and II above with a cyclic [(R 2 ) 2 SiO] 4 , or linear HO[(R 2 ) 2 SiO] n H, compound, or with a hexaalkyl disiloxane in the case of compounds of formula II, and then in a second step carrying out a hydrosilylation reaction according to one of the general reactions identified as V and VI respectively: and wherein R, R 1 , R 21 w, x, y and z have the same meaning as they have in formulas I and II above.

Claim 2

A method for preparing an alkoxysilyl functional silicone represented by a formula selected from the group consisting of: and wherein R is an alkyl or an acyl hydrocarbon radical having from one to four carbon atoms, preferably a methyl radical; R i is an alkyl radical of from one to two carbon atoms or a mixture thereof, preferably a methyl radical; R 2 is an alkyl radical having from one to three carbon atoms, mixtures thereof, or an aryl radical selected from the group consisting of phenyl, benzyl and phenylethyl, mixtures thereof, or a mixture of said alkyl and aryl radicals, preferably methyl radical; w is an integer of from 2 to about 20, preferably either 2 or 3; x is an integer of from 0 to 2, preferably either 0 or 1; y is an integer of an average of at least 6, preferably of an average of from 6 to about 1000 and z is an integer of an average of at least 1, preferably of an average of from 1 to about 100, comprising reacting in a first step a silanic hydrogen functional silicone precursor selected from the group consisting of and wherein R 1 , R 2 , y and z have the same meaning as in formulas I and II above with a cyclic [(R 2 ) 2 SiO] 4 , or linear HO[(R 2 ) 2 SiO] n H, compound, or with a hexaalkyl disiloxane in the case of compounds of formula II, and then in a second step carrying out a hydrosilylation reaction according to one of the general reactions identified as V and VI respectively: and wherein R, R 1 , R 21 w, x, y and z have the same meaning as they have in formulas I and II above.

Claim 3

A method according to claim wherein the synthesis is carried out at elevated temperatures of from about 25°C to about 175°C, preferably from about 80 to 110°C.
