ABSTRACT:
Polyisocyanurate polymers are prepared by polymerization of polyisocyanates in organic solvents employing trimerization catalysts. The polyisocyanates are reacted with halogenated alcohols subsequent to polymerization. These polymers may be dispersed in polyols for the preparation of cellular and non-cellular polyurethane products having improved flame retardant physical properties.
