Abstract
A chiral poly(3-substituted isobutyl D-aspartate) 12 was synthesized b y polymerization of the chiral beta-lactam 11 derived from D-glycerald ehyde. The new polyamide was characterized by elemental analyses, and infrared, H-1- and C-13 nuclear magnetic resonance spectroscopies. The molecular weight was estimated as 543000 and 230000 on the basis of v iscosimetric measurements and gel-permeation chromatography, respectiv ely. Polyamide 12 is soluble in a variety of organic solvents includin g chloroform.
