Abstract

A chiral poly(3‐substituted isobutyl D‐aspartate) 12 was synthesized by polymerization of the chiral β‐lactam 11 derived from D‐glyceraldehyde. The new polyamide was characterized by elemental analyses, and infrared, ^1^H‐ and ^13^C nuclear magnetic resonance spectroscopies. The molecular weight was estimated as 543 000 and 230 000 on the basis of viscosimetric measurements and gel‐permeation chromatography, respectively. Polyamide 12 is soluble in a variety of organic solvents including chloroform.
