Abstract:
A polysiloxane composition having the formula ##STR8##wherein:R.sub.1, which can be the same or different, is selected from R.sub.2, a diamine containing group of the formula (CH.sub.2).sub.n --F.sub.n1 --B.sub.n2 --F--NH.sub.2 and a pyrrolidone-containing group of the general formula: ##STR9##wherein at least one R.sub.1 is a pyrrolidone containing ester or amide derivative group as shown;D is nitrogen or oxygen;x is 1 or 2 with the proviso that if D is oxygen, x is 1R.sub.5 is linear or branched, saturated or unsaturated, substituted or unsubstituted alkyl of 6 to 22 carbon atoms or capped or uncapped polyoxyalkylene of 6 to 22 carbon atoms;F is linear or branched alkylene of 1-12 carbon atoms;B is --NR.sub.9, sulfur or oxygen wherein R.sub.9 is hydrogen or an alkyl;n is zero or 2; n.sup.1 is zero or 1 and n.sup.2 is zero or 1; with the proviso that when n is zero and n.sup.2 is 1, n.sup.1 is 1, when n is 2 and n.sup.2 is 1, n.sup.1 is 0 or 1 an when n is 2 and n.sup.2 is 0, n.sup.1 is zero;R.sub.2 can be the same or different and is selected from alkyl, aryl alkenyl or alkynyl;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; with the proviso that when a is zero, all R.sub.1 can be the same or different pyrrolidone-containing groups or only the terminal R.sub.1 groups are R.sub.2 groups, and R.sub.3 can be the same or different than the R.sub.2 groups.
