The stereospecific polymerization of some optically active α‐olefins and the fractionation by solvent extraction of the polymers thus obtained are described and the dependence of the optical activity of the polymers in dilute solution on their stereoregularity and on the temperature is investigated.
The optical rotatory dispersion between 650 and 320 mμ of the polymers is normal and the chromophoric system responsible for the rotation in the polymers is in the wavelengths range of the ultimate absorption band of the low molecular weight paraffines.
The optical activity of the most stereoregular fractions of the polymers can be successfully calculated using methods already known for the low molecular weight compounds.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
