| abstract |
The invention sets forth novel telechelic (terminally functional) prepolymers which may be reacted to form curable epoxides. On account of the incorporation of saturated elastomer chains into the prepolymers improved epoxides arise having increased moisture resistance and less brittleness than conventional epoxides. These prepolymers may be straight chain or three-armed star, emanating from a common phenyl ring nucleus. Molecular weights of the prepolymers range from about 700 to 50,000 (linear) and from about 1000 to about 75,000 (three-arm star). The epoxides are useful as coatings, in adhesives, as additives, and the like. |
