Abstract:
A method for treating a cellulose-containing substrate comprising contacting a silicone composition with the cellulose-containing substrate in the presence of a base; wherein the silicone composition comprises at least one polysiloxane or silicone resin containing at least one reactive functional group, the silicone composition having the formulaMaMâ€²bDcDâ€²dTeTâ€²fQg where the subscripts a, b, c, d, e, f and g are zero or a positive integer, subject to the limitation that the sum of the subscripts b, d and f is at least one; where M has the formula:R13SiO1/2, Mâ€² has the formula:(X)hR23-hSiO1/2, D has the formula:R32SiO2/2, Dâ€² has the formula:(X)(2-i)iR4SiO2/2, T has the formula:R5SiO3/2, Tâ€² has the formula:â€ƒ(X)SiO3/2,and Q has the formula SiO4/2, where subscript h is in a range between 1 and 3; subscript i is 0 or 1; each R1, R2, R3, R4, R5 is independently at each occurrence a hydrogen atom, C1-30 alkyl, C1-22 alkoxy, C2-22 alkenyl, C6-14 aryl, C6-22 alkyl-substituted aryl, C6-22 aralkyl, C1-22 fluoroalkyl, polyether, or amino alkyl; and each X is the reactive group; and curing the silicone composition on the cellulose-containing substrate at a temperature in a range between about 25Â° C. and about 200Â° C.
