ABSTRACT:
Block copolymers are prepared by reacting a polyester resin or polyol with a hydroxyl or carboxyl functional mercaptan and subsequently reacting the blocked polyester or polyol in the presence of oxygen, with selected vinyl monomers such as diacetone acrylamide, acrylic acid, 2-hydroxyethyl acrylate and the like. Such block copolymers provide for coating compositions having physical properties which render them useful as protective and/or decorative films.
