/ AROMATIC POLYOL END-CAPPED UNSATURATED POLYETHERESTER RESINS AND RESIN COMPOSITIONS CONTAINING THE SAME HAVING IMPROVED CHEMICAL AND/OR WATER RESISTANCE

摘要

The present invention relates to unsaturated polyetherester resins useful as intermediates for preparing curable thermosetting resin compositions, intermediates of curable thermosetting resin compositions, fiber reinforced polymer composites, gel coated fiber reinforced composites and skin laminates for gel coated polymer laminates, and these It relates to a method for producing. Unsaturated polyetherester resins react one or more acid-terminated unsaturated polyetherester resins with one or more aromatic polyols having one or more non-primary hydroxyl groups so that at least some of the end capped unsaturated polyols are aromatic polyols. It is possible to produce and obtain a polyether ester resin. The disclosed processes, compositions, methods and uses improve the chemical and / or water resistance of resin compositions, especially composite materials with gel coating. These improvements have particular importance in environments exposed to chemicals such as outdoor and marine applications, bath and shower stalls, and industrial and commercial applications.
