There is disclosed a group of poly(ester-amide) compositions which possess unexpectedly good low temperature adhesive properties with respect to vinyl based substrates. These poly(ester-amide) compositions are the reaction product of a polymeric fatty acid, with an organic diamine, dicarboxylic acid and an alkanolamine having the general formula:-
wherein R2 represents alkylene of 2 to 8 carbons, and R, is selected from the group consisting of hydrogen and a monovalent moiety of the formula:-
wherein R3 is selected from hydroxyl and amino groups.
The term "alkylene of 2 to 8 carbons" as used throughout the specification and claims means a divalent moeity of the formula:-
wherein n is an integer of from 0 to 6. N-(2-hydroxyethyl)-piperazine is a preferred compound of the alkanolamine group.
