Abstract The ability of lactams to undergo ring-opening polymerization largely depends on the ring size, substitution and presence of heteroatoms in the lactam ring. The heat of polymerization varies with ring size from practically zero up to 20 kcal/mol. Also the entropy of polymerization can vary in a much broader range than for, e.g.

Oxidizability of lactams and lactam‐based polyamides
Die Angewandte Makromolekulare Chemie, 1997AbstractIn the chain oxidation of N‐alkylamides with molecular oxygen, propagation is the ratedetermining step under conditions when the oxidation rate is independent of oxygen pressure. The oxidizability of lactams and lactam‐based polyamides correlates with the energy of the formation of N‐alkylamide radical by abstraction of hydrogen from the ...

Cationic polymerization and copolymerization of lactams and lactam derivatives
Makromolekulare Chemie. Macromolecular Symposia, 1988AbstractLactams and lactam derivatives may be polymerized by various types of processes, but only the cationic mechanisms provide suitable pathways for the polymerization of all types of lactam monomers. Therefore, the cationic polymerization is predestinated for the synthesis of their copolymers.
