Abstract
Optically active copolymers of (—)menthyl acrylate (MtA) with 4-hydroxybenzophenone acrylate (ABP) have been prepared by radical initiation. Reactivity ratios, mean sequence lengths and the statistical distribution of the sequence lengths of both co-units have been evaluated. Chiroptical properties of the copolymers indicate that a chiral perturbation of side-chain benzophenone chromophores occurs, due to the dissymetric arrangement of the macromolecules. C.d. data in the spectral region connected with the nåπ°∗ electronic transition of benzophenone chromophore, combined with statistical distribution of sequence lengths of monomeric units in the macromolecules suggest that the observed ellipticity is essentially due to the isolated ABP units, inserted in blocks of chiral MtA units.
