## Abstract

Organosilane and organosiloxane monomers are provided containing at least one carboxyl ester functional group represented by the formula: wherein: R which can be the same or different are hydrolyzable groups; R1 which can be the same or different, are selected from substituted or unsubstituted alkyl, cycloalkyl, substituted or unsubstituted aryl, alkenyl, alkynyl or —OSi(R1)3; x is zero to 3; R2 is linear or branched alkylene of 1-12 carbon atoms; B is —NR10, wherein R10 is hydrogen or a diacarboxylic ester group of the formula —CH2—CH(COOR6)—CH2COOR6; R5 is hydrogen or alkyl; R6 is alkyl; F is linear or branched alkylene of 1-10 carbon atoms;
