Polyaldaramide polymers useful for films and adhesives

Film-forming and adhesive aldaramide polymers having the general formula:

• {[GLU--NH--(RYR.sup.1).sub.n --(CR.sup.2 R.sup.3).sub.n' --NH--].sub.a [--XYL--NH--(RYR.sup.1).sub.n --(CR.sup.2 R.sup.3).sub.n, --NH--].sub.b --]GAL--NH--(RYR.sup.1).sub.n --(CR.sup.2 R.sup.3).sub.n, --NH--].sub.c }.sub.x ##STR3## each of a, b and c may be zero and the sum a+b+c must be greater than zero, with the proviso that the value of c cannot be greater than the sum a+b;
• each individual n is individually 1 or 2;
• each individual R is selected individually from the group of divalent radicals consisting of alkylene, alkenylene, aryl- and alkyl-substituted alkylene and alkenylene, and --R.sup.4 -(arylene)-R.sup.4 -- and --R.sup.4 -(alkyl- and alkenyl-substituted arylene)-R.sup.4 --, where each individual R.sup.4 is selected individually from the group consisting of alkylene having from 1-4 carbon atoms;
• each individual R.sup.1 is selected individually from the group consisting of R or a valence bond;
• each individual R.sup.2 and R.sup.3 is selected individually from the group consisting of hydrogen, alkyl, alkenyl, alkynyl, aryl, aryl-substituted alkyl and alkenyl, and alkyl- and alkenyl-substituted aryl;
• each individual n' may individually be zero or an integer from 1-3 with the proviso that when R.sup.1 is a valence bond n' must be at least two;
• each individual Y is selected individually from the group consisting of --O--, --S--, --NR.sup.5 --, and --PR.sup.5 --, wherein each individual R.sup.5 is selected individually from the group consisting of hydrogen, alkyl, alkenyl, aryl, aralkyl and alkaryl;
