Abstract

Abstract Copolymers of acetamidoethylene are disclosed. These materials have randomly distributed units represented by the formula ##STR1## wherein R is one or more radicals selected from the group ##STR2## and the C 1 to C 6 carboxylic acid esters thereof, ##STR3## wherein R 1 is hydrogen or a C 1 to C 6 alkyl, and R 2 is a C 1 to C 6 alky; x and y are numbers greater than zero which total to 1.00; the ratio of x to y from about 0.05:0.95 to about 0.95:0.05; and n is an integer from about 14 to about 10,000. The copolymers are useful as epoxy resin curing agents, as components of protective or decorative coatings, and as intermediates in the formation of vinylamine group-containing copolymers having the formulae ##STR4## wherein x, y and n are as previously defined, x' plus z equals x and R 3 is one or more of the radicals selected from the group ##STR5## wherein R 1 and R 2 are as previously defined.
