HYDROXYL-TERMINATED OR CARBOXYLIC ACID-TERMINATED REACTIVE MONOMER COMPOSITIONS, THEIR PREPARATION AND THEIR USE
The present invention relates to new reactive monomer compositions that have a plurality of reactive, functional moieties, such as one or both of a hydroxyl moiety or a carboxylic acid moiety. The present invention also further relates to use of such reactive monomer compositions as a component of curable coating compositions, especially curable powder coating compositions.
