IPC: C08F20/00
Filed: 1998-08-25
Abstract: Apparatuses and methods are disclosed for the production of a polyester/epoxy copolymer that can be applied as a liquid to a surface prior to being cured. The method of preparing the polyester/epoxy copolymer includes mixing maleic acid with dicyclopentadiene to produce a ten-carbon double ring ester, promoting esterification with the addition of a source of hydroxyl, such as an alcohol or a glycol, to a desired acid number and reacting with an epoxy. Optionally, a source of unsaturation may also be added. Examples include excess maleic anhydride, fumaric acid, excess ten-carbon ester, nadic anhydride, or tetrahydrophthalic acid. Electrical components of the present invention include a cured coating of the copolymer of the present invention over at least a portion of the component.
