摘要： 1. A FIRS-RESISTANT POLYURETHANE FOAM PREPARED BY INCORPORATING INTO THE REACTANT MIXTURE USED TO PREPARE THE POLYURETHAND FOAM-THE SAID REACTANT MIXTURE CONSISTING ESSENTIALLY OF AN ORGANIC DI- OR POLYISOCYANATE, A POLYETHERPOLYOL COMPOUND HAVING A HYDROXYL NUMBER OF BETWEEN 46 MILLIGRAMS AND 520 MILLIGRAMS OF KOH/GRAM OR A POLYESTERPOLYOL COMPOUND HAVING A HYDROXYL NUMBER OF 60 MILLIGRAMS OF KOH/GRAM AND HAVING AN ACTIVATOR, AN EXPANDING AGENT AND A CELL REGULATOR THEREIN-A FIRE RESISTANCE IMPARTING PRODUCT IN AN AMOUNT BETWEEN ABOUT 5 AND 50 WEIGHT PERCENT BASED ON THE AMOUNT OF THE POLYETHER OF POLYESTER POLYOL COMPOUND THE PRODUCT CONSISTING OF A COMPOUND OF THE GENERAL FORMULA (I)

R1-O-P(=(O)A)(-O-R1)-R2-O-(P(=(O)A)(-O-R1)-R2-O)N-P(=O)

(-O-R1)2

IN WHICH A STANDS FOR 1 OR 0 AND 1 N STANDS FOR A NUMBER OF BETWEEN 0 AND 4, R1 STANDS FOR AT LEAST ONE HALOGENATED ALKYL RADICAL SELECTED FROM THE GROUP CONSISTING OF A 2-CHLORETHYL RADICAL AND A 2,3-DIBROMOPROPYL RADICAL, AND AT LEAST ONE HYLDROXYL-CONTAINING RADICAL OF THE GENERAL FORMULA (II)

-(CH(-R3)-CH(-R4)-O)M-H

AND R2 STANDS FOR A RADICAL OF THE GENERAL FORMULA (III)

-(O-CH(-R3)-CH(-R4))M-

R3, R4 IN FORMULAE (II) AND (III) ABOVE STANDING FOR A HYDROGEN ATOM, A METHYL RADICAL OR A CHLOROMETHYL RADICAL AND M STANDING FOR A WHOLE NUMBER OF BETWEEN 1 AND 4.
