    Abstract: 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.

    Abstract: The invention provides a granulate comprising particles having sizes substantially within the range 0.15 to 1.25 mm, the granulate consisting of: (a) about 1 to 99 weight % of partially or completely hydrated sodium tripolyphosphate containing water of hydration in a proportion of at least about 10 weight %, based on the theoretically possible water content, the anhydrous sodium tripolyphosphate containing about 20 to 90 weight % of phase-I-material prior to its being hydrated, the balance being phase-II, and (b) about 99 to 1 weight % of a water-insoluble alumino silicate ion exchanger material of the general formula (Cat2/nO)x.Me2O3.(SiO2)y.zH2O in which Cat stands for a calcium exchangeable cation with the valency n, x is 0.7 to 1.5, Me stands for boron or aluminum, y is 0.8 to 6, and z is 1.8 to 13.5. The invention also includes a spray process for making a granulate as just specified. The present granulate can be made with a particle size distribution which gives it particular utility as a detergent composition constituent.
