## Abstract The conformation of several samples of poly(α,β‐L‐Asp) with a molar fraction of β‐bonds ranging from 0.1 to 0.55 was investigated by means of ir and CD spectroscopy and potentiometric titration and compared with the results obtained previously with poly(α‐L‐Asp). All samples investigate
## Abstract The conformation of poly(α‐L‐aspartic acid) was investigated on a sample in which β‐bonds were not detected. CD and ir spectroscopy showed that poly(α‐L‐aspartic acid) passes through a conformational change induced by changes of the degree of ionization that is accompanied by precipitat
## Abstract Poly‐β‐1‐naphthylmethyl‐L‐aspartate and copolymers of β‐1‐naphthylmethyl‐L‐aspartate and γ‐benzyl‐L‐glutamate were prepared. From the results obtained by a study of infrared and circular dichroism spectra, poly‐β‐1‐naphthylmethyl‐L‐aspartate was found to be a left‐handed α‐helix both in
