Abstract of the Disclosure Polyisocyanurate polymers are prepared by poly- merization of polyisocyanates in organic solvents employing trimerization catalysts. The polyisocyanates are reacted with monofunctional active hydrogen compounds prior to polymerization or subsequent to the polymerization. These polymers may be dispersed in polyols for the preparation of cellular and non-cellular polyurethane products having improved physical properties.
