Abstract:
A linear polydialkylorganosiloxane having polyoxyalkylene and amino-functional groups which additionally has terminal alkoxy groups, of the general formula (I) where a=5 to 500, b=1 to 100, the radicals R1=identical or different aliphatic or aromatic hydrocarbon radicals having up to 8 carbon atoms, and R2&boxH;R1, R2a or R2b, with the proviso that on statistical average a radical R2a is present in at least every tenth siloxane repeating unit, and at least one radical R2b is present in each siloxane repeating unit, where the radical R2a is selected from the radicals of an amino-functional group of the general formula (II) â€”[(R4)câ€”NR5]dâ€”R6 â€ƒwhere R4=a divalent C1 to C12 hydrocarbon radical, an â€”OCH2CH2â€” group or an OCH2CH(CH3)â€” group, R5=a monovalent C1 to C12 hydrocarbon radical or a hydrogen atom, R6=a monovalent aliphatic or aromatic, optionally substituted C1 to C12 hydrocarbon radical or a hydrogen atom, where c=1 to 10, and d=1 to 5, the radical R2b is a polyoxyalkylene group of the general formula (III) â€”(CH2)e(OC2H4)f(OC3H6)gOR6 where e=2 to 10, f=2 to 20, g=0 to 20, and R3&boxH;R1 or a group of the general formula (IV) â€”OR1 â€ƒwith the proviso that on statistical average at least one radical of the general formula (IV) is present on the siloxane backbone.
