Abstract
Optically-active, amphiphilic, free-radical addition copolymers having an optically-active hydrophobic portion and an ionic hydrophilic portion are effective resolving agents. This utility is based on a unique combination of properties, viz., water solubility, chirality and amphiphilicity, i.e., having a dual hydrophobic and hydrophilic nature.
