Abstract
Living anionic polymers of unsaturated monomers are conveniently capped with oxetane or an alkyl substituted oxetane to provide terminal primary hydroxyl groups. The hydroxyl capped polymers are useful in making coatings, sealants, binders, and block copolymers with polyesters, polyamides, and polycarbonates.
