Abstract:
A polysiloxane composition having the formula ##STR7## wherein: R is selected from R.sub.2 or --OR.sub.9 wherein R.sub.9 is hydrogen or alkyl;R.sub.1, which can be the same or different, is selected from R.sub.2, a diamine containing group of the formula --F.sub.1 --NR.sub.9 --F--NH.sub.2 and a pyrrolidone-containing functional carboxyl group of the general formula: ##STR8## wherein at least one R.sub.1 is a pyrrolidone containing functional carboxyl group or ester derivative thereof as shown;R.sub.2 is as defined below;R.sub.5 is hydrogen lower alkyl (C.sub.1-6) or alkali metal;F.sub.1 is linear or branched alkylene of 1-12 carbon atoms;F is linear or branched alkylene of 1-10 carbon atoms;B is --NR.sub.7, wherein R.sub.7 is hydrogen or a dicarboxylic group of the formula --CH.sub.2 --CH(COOR.sub.9)--CH.sub.2 COOR.sub.2 wherein R.sub.9 is hydrogen or an alkyl, with the proviso that at least 25% of R.sub.7 is a dicarboxylic group;R.sub.2 can be the same or different and is selected from alkyl, aryl or olefinic;R.sub.3 and R.sub.4, which may be the same or different are selected from alkyl, aryl, capped or uncapped polyoxyalkylene, alkaryl, aralkylene or alkenyl;a is an integer from 0 to 50,000; andb is an integer from 0 to 100.
