Abstract
Novel polymers are prepared from at least one cyanoacetamide monomer having the formula: ##STR1## where R.sub.1 is --CH.sub.3, --(CH.sub.2).sub.m CH.sub.3 or --H; R.sub.2 and R.sub.3 independently are --H, (C.sub.1 -C.sub.4) alkyl or aryl; R.sub.4 is --CH.sub.3, --(CH.sub.2).sub.n CH.sub.3 or --H; m is 1 to 10; n is 1 to 10; and x is 1 to 20. These polymers can be readily reacted by a carbon-Michael addition reaction with carbon-Michael acceptors, such as polyfunctional acrylates, methacrylates, fumarates, maleates and aopates to form crosslinked polymer compositions.
