Title:
酸で触媒された水とエポキシ樹脂の共重合及びその使用
Document Type and Number:
Japanese Patent JP4143057
Kind Code:
B2
Abstract:
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.
