A new resinous polymer containing amide linkages wherein the amide nitrogen is part of the polymer backbone is prepared by polymerizing at least one alpha, beta-unsaturated monocarboxylic acid or ammonium salt thereof in the presence of ammonia. The polymers are suitable for use as fibres, plastics films and moulding resins. …<??>A random copolymer containing the following structural units …<CHEM>… wherein R1, R2 and R3 are each independently selected from the group consisting of:… (1) hydrogen;… (2) C1-30 alkyl;… (3) 5 to 7 member nitrogen containing heterocyclic radicals;… (4) mono and poly carbocyclic radicals containing up to 30 carbon atoms; and… (5) halides …<??>T is a branched chain site, M is OH, ONH4, ONH2T or NHT and x, y, and z are independently the number of such structural units in the resinous polymer of the invention is also disclosed. |
