Abstract
This article examines the anionic polymerization of lauryl lactam into polyamide 12 and the copolymerization of lauryl lactam with a diisocyanate‐end‐capped polycaprolactone used to produce a poly(ester amide) block copolymer. The molecular weights of the polyester polyols used in the preparation of the diisocyanate‐end‐capped polycaprolactone were varied. The products were characterized with Fourier transform infrared spectroscopy and differential scanning calorimetry, and the mechanical properties were measured in a mechanical tester. The influence of the polyol molecular weight was considered. © 2003 Wiley Periodicals, Inc. J Appl Polym Sci 90: 3797–3805, 2003
