Latest Patents

Ronald J Lewarchiki holds a patent for a "Polyester oligomer and high solids thermosetting coatings." This invention involves an essentially linear polyester oligomer that has hydroxyl and carboxyl terminal groups, which are crucial for subsequent curing processes. The production of this polyester oligomer begins with the adduction of approximately equimolar amounts of a diol with two primary hydroxyl groups and a dicarboxylic acid anhydride to form a hydroxy acid. The carboxyl groups of this hydroxy acid are then esterified by reacting with a diol that has one primary and one secondary hydroxyl group. This process results in a hydroxyl-terminated oligomer, which is further adducted with a polycarboxylic acid monoanhydride. The final product is a polyester oligomer that exhibits low solution viscosity at high resin solids content and high reactivity, allowing for low-temperature curing with aminoplast resins.
