Abstract
Investigations were made of ultraviolet, optical rotatory dispersion, and circular dichroism of acrylic acid − (+) N-s-butyl-N-methylacrylamide random copolymers of different composition (COP Y, with Y=percentage of achiral acid repeat units). The nonlinear composition-dependence of optical rotatory dispersion and circular dichroism spectra is discussed with regard to the properties of homopolymers corresponding to amide and acid repeating units, i.e., (−) poly[N-s-butyl-N-methylacrylamide] and poly(acrylic acid), respectively. It is shown that some of the achiral acid units were asymmetrically perturbed because of a neighboring effect of chiral amide units. This finding well accounts for the nonlinear-composition-dependent chiroptical properties of COP Y, in spite of their random-coil structure in solution.
