The present invention relates to an amino-functional polysiloxane of formula (1)n nwherein each R 1 is independently selected from the group comprising alkyl and arylnradicals, each R 2 is independently selected from the group comprising hydrogen, alkylnand aryl radicals, n is selected so that the molecular weight for the functionalnpolysiloxane is in the range of from 400 to 10,000 and R 3 is a bivalent radical orn-O-R 3 -NH-R 5 is hydroxy or alkoxy, and R 5 is selected from the group comprisingnhydrogen, aminoalkyl, aminoalkenyl, aminoaryl, aminocycloalkyl radical, optionallynsubstituted by alkyl, aryl, cycloalkyl, halogen, hydroxy, alkoxy, thioalkyl, amino, aminonderivatives, amido, amidoxy, nitro, cyano, keto, acyl derivatives, acyloxy derivatives,ncarboxy, ester, ether, esteroxy, heterocycle, alkenyl or alkynyl and wherein 0 to 90 % ofn-O-R 3 -NH-R 5 is hydroxy or alkoxy. |
