Acid catalyzed copolymerization of water and epoxy resin and uses thereof

   
   

Non-gelled polymeric polyols are prepared by the acid catalyzed copolymerization of epoxy resins and water. When the starting resin is an epoxy resin derived from bisphenol-A, the resulting product has much lower levels of bisphenol-A and diglycidyl ether of bisphenol-A (DGEBA) compared to traditional epoxy resins of comparable molecular weight prepared by the advancement process. The product can be cured with OH reactive crosslinkers such as amino resins and polyisocyanates to yield thermosetting coatings with useful properties.

Cuando la resina que comienza es una resina de epoxy derivada de bisphenol-A, el producto que resulta tiene niveles mucho más bajos del éter del bisphenol-A y del diglycidyl del bisphenol-A (DGEBA) comparado a las resinas de epoxy tradicionales del peso molecular comparable preparado por el proceso del adelanto. El producto se puede curar con los crosslinkers reactivos del OH tales como resinas y polyisocyanates amino para rendir capas termoendurecibles con las características útiles.
