The present invention relates to an organo-functional polysiloxane of
formula (1) wherein each R.sup.1 is independently selected from alkyl or
aryl radicals, each R.sup.2 is independently selected from hydrogen,
alkyl or aryl radicals, n is selected so that the molecular weight for
the organo-functional polysiloxane is in the range of from 400 to 10,000,
R.sup.3 is a bivalent radical or --O--W--(X).sub.z is hydroxy or alkoxy,
z is 1, 2 or 3 and X is a reactive functional group for reacting with
amine radicals and wherein 0 to 90% of --O--R.sup.3--(X).sub.z is hydroxy
or alkoxy ##STR00001##
