Polyamidopolyfunctional amines of the following formula are described: (see figure I) where R is independently hydrogen or lower alkyl of 1 to 4 carbon atoms; R' is an alkyl group if k is 1, or an alkylene group if k is greater than 1; where R' has 2 to 18 carbon atoms; R" is independently lower alkylene of 2 to 4 carbon atoms; R"' is independently straight or branched lower alkylene of 2 to 6 carbon atoms; x is independently 1 to 200; y is independently 1 to 300; z is independently 1 to 200; p is independently 2 to 11; and k is from 1 to 8; where the x and z groups may be distributed in blocks or randomly. These compositions are made by reacting a cyclic lactam with a polyether- polyamine. Incorporation. of increasing quantities of the polyetherpoly- amine did not decrease the crystalline melting point (T m) of the resulting copolymer. The polyamidopolyfunctional amines (poly(amide-ether- amide) triblock copolymers) have a relatively low modulus and retain higher use temperatures than current polyetheramide segment block copolymers. The polyamidopolyether amines may be further intercon- nected through reaction with dicarboxylic acids, esters and the like.
