Abstract
A method for the preparation of cast or transfer molded rigid polyisocyanurate polymer composition by conveying from a mixing chamber into a mold cavity of desired configuration to react at temperatures of from about ambient to about 140.degree. C. a reaction mixture of an organic di- or polyisocyanate, a cyclic alkylene carbonate and a soluble adduct of a tertiary amine and a cyclic alkylene carbonate as catalyst.
