Action de différentes especes d'amorçage dans la polymérisation hydrolytique du dodécanelactame‐12

The study of the initiation step in the hydrolytic polymerization of 12‐dodecanelactam showed the prominent role of chain‐ends in the monomer consumption and especially that of amino end groups. Different initiators, dodecylamine hydrochloride, 12‐aminododecanoic acid, or lauric acid, where employed and in some experiments water was added. This led to the formation of new end groups and thus to an enhancement of the monomer consumption rate. It could be shown that during this process large changes in the polymer chain length distribution occur.
