ABSTRACT:
Copolymers of vinyl aromatic monomers and propoxylated allyl alcohols having an average of 2 or less oxypropylene groups are disclosed. The copolymers, which have hydroxyl numbers of 80-260 mg KOH/g and number average molecular weights from 500-3500, are particularly useful for polyurethanes, alkyd resins and coatings, melamine-based coatings, and unsaturated polyester resins.
