Abstract:
Organosiloxane compounds and oligomers containing at least one carboxylic ester functional group are represented by the formula: ##STR15##wherein:R, which can be the same or different are hydrolyzable groups;R.sup.1, which can the same or different, are selected from substituted or unsubstituted alkyl, cycloalkyl, substituted or unsubstituted aryl, aralkyl, alkenyl, alkynyl or --O--Si(R.sup.1).sub.3 groups or mixtures of the same;R.sup.7 and R.sup.8, which may be the same or different, are selected from alkyl, aryl, capped or uncapped polyoxyalkylene, alkaryl, aralkylene, alkenyl or alkynyl or mixtures of the same;M, which can be the same or different is selected from hydrogen, R, R.sup.1 or CH.sub.2 --CHR.sup.5 --R.sup.2 --B--F--R.sup.3 with the proviso that at least one M group is CH.sub.2 --CHR.sup.5 --R.sup.2 --B--F--R.sup.3 ;R.sub.5 is hydrogen or alkyly is zero to 2;B is --NR.sup.10 ;R.sup.10 is a diacarboxylic ester group of the formula --CH.sub.2 --CH(COOR.sup.6)--CH.sub.2 COOR.sup.6 ;R.sup.6 is alkyl;R.sup.2 is linear or branched alkylene of 1-12 carbon atoms;F is linear or branched alkylene of 1-10 carbon atoms; ##STR16##a is from zero to 10; andb is from zero to 10.
