| titleOfInvention | Polyether-epoxy polymer composition |
| abstract | Polyether-epoxy polymer compositions are disclosed. The composition contains the reaction product of a polyepoxy compound and a polyol composition containing a polyether polyol. The ratio of epoxy equivalents to hydroxyl equivalents is in the range of 0.5:1 to 3:1. The polyether-epoxy composition has a T g in the range of -40°C to 60°C. The polyether polyols have a hydroxyl number in the range of 150 to 800 mg KOH/g and an average hydroxyl functionality in the range of 3.5 to 8.0. In some aspects, the polyol composition also contains a polyester polyol. Also disclosed are low temperature and high temperature methods for preparing polyether-epoxy compositions catalyzed by bases or Lewis acids. In a simple and innovative method, polymerized from readily available starting materials, independent of polyamines or polyisocyanates, the polymers are used in coatings, elastomers, adhesives, sealants and other value product. |
