ISOCYANATE TERMINATED OUASI-PREPOLYMERS USEFUL FOR PREPARING URETHANE-GROUP-CONTAINING POLYISOCYANURATE FOAMS HAVING LOW FRIABILITY Abstract of the Disclosure Flame retardant intumescent polyisocyanurate rigid foams are prepared by trimerizing isocyanate-terminated quasi-prepolymers containing predominately urethane linkages prepared by reacting an organic polyisocyanate with poly- ester polyols derived from the transesterification of dimethyl terephthalate process residue. The solvent blown rigid polyisocyanurate foams have exceptionally low fri- ability.
