ABSTRACT:
Non-gelled polymeric polyols are prepared by the acid catalyzed copolymerization of water, tetrahydrofuran and multifunctional epoxy resins. The polyols can be cured with OH reactive crosslinkers such as amino resins and polyisocyanates to yield thermosetting coatings with useful properties.
