Abstract
Hydroxyl functional oil polyol acrylic graft copolymers are disclosed which can be used to produce coating compositions and coated surfaces. In some embodiments, the coating compositions are used to coat substrates such as packaging materials and the like for the storage of food and beverages. The hydroxyl functional oil polyol acrylic graft copolymers can be prepared by heating an epoxidized vegetable oil and a hydroxyl functional material in the presence of an acid catalyst to form a hydroxyl functional oil polyol, and reacting the hydroxyl functional oil polyol with a mixture of an ethylenically unsaturated monomer component in the presence of an initiator to form the hydroxyl functional oil polyol acrylic graft copolymer. Coating compositions can be prepared by crosslinking the hydroxyl functional oil polyol acrylic graft copolymers with a crosslinker.
