Abstract
A method of preparing functional materials for coatings, which may be polymers, oligomers, or compounds, includes polymerizing an alpha-methylene lactone that is reacted, before or after polymerization, with a hydroxy-functional reactant. Coating can be prepared with the reaction products.
Claims28
A method of preparing a coating composition, comprising
- reacting together an alpha-methylene lactone and an active hydrogen-functional reactant to form a first reaction product;
- addition polymerizing the first product to form a polymer;
- and
- incorporating the polymer into a coating composition.
