Abstract
Abstract Tris(2-hydroxyalkyl)isocyanurates are reacted with alkylene oxides to obtain tris( Beta -hydroxyalkyl)isocyanurate-alkylene oxide adducts, which can be polymerized with polycarboxylic acids. The resultant polyesters are useful as electrical insulating material in wire enamels and varnishes, casting resins, and for making ester-imide copolymers. High alkylene oxide-content isocyanurates are good functional fluids and lubricants.
