    Abstract: 1443117 Polyurethane foams HOECHST AG 8 Nov 1974 [9 Nov 1973] 48427/74 Heading C3R [Also in Division C2] Polyurethane foams are flame retarded by incorporating in the foam-forming mixture a polyol of Formula I where A is A 1 is B is Cl-CH 2 -CH 2 -O-, R is optionally halogen-substituted C 2-6 alkylene, phenylene or diphenylenemethane optionally substituted by alkyl or haloalkyl on the methylene C atom, one of R 1 and R 2 is H and the other is C 1-4 alkyl or haloalkyl or R 1 and R 2 are each C 1-4 alkyl or haloalkyl, x + y is 0À1 to 3 and n 1 or 2. In an example the polyurethane is formed from a partially branched polyether polyol based on propylene oxide and toluylene diisocyanate (80 : 20 blend of the 2,4- and 2,6- isomers).

    Abstract: Self-extinguishing laminates are made by an improved process, wherein individual layers of a carrier material are impregnated with a thermosetting phenolic resin containing a flame-retardant agent and the impregnated layers are placed one above another and bonded together by compressing them at elevated temperature and under elevated pressure to give a hardened laminate. More specifically, finely pulverulent phosphorus pentanitride as a flame-retarding agent is dispersed in the plasticized or non-plasticized thermosetting phenolic resin, with or without a diluent; the phenolic resin, based on its solid matter content, and the phosphorus pentanitride being used in an approximate ratio by weight of 100:4 to 100:15; and the phenolic resin, based on its solid matter content, and the carrier being used in an approximate ratio by weight of 100:80 to 100:150.

    Abstract: STABILIZED RED PHOSPHORUS AND PROCESS FOR MAKING IT Production of stabilized pulverulent red phosphorus. The phosphorus so stabilized comprises a homogeneous blend of red phosphorus particles with a size of at most about 2 mm and a metal compound of the second or third group of the Periodic System as an oxidation stabilizer, wherein the metal compound is the aluminum, calcium or zinc salt of a phosphinic acid of the general formula in which R1 and R2 each stand for an alkyl, cycloalkyl, aryl or aralkyl group having 1 to 20 carbon atoms, the metal compound being present in the homogeneous blend in a proportion of about 0.5 to 5 weight %.
