Abstract: A preferred rigid thermoplastic resin composition having high impact strength and resistance to thermal distortion includes a vinyl chloride resin/polycarbonate alloy and at least 3 parts by weight of butadiene-modified acrylic per 100 parts by weight of the alloy. A particularly preferred thermoplastic resin composition includes the alloy and both butadiene-modified acrylic and ethylene-vinyl acetate copolymer.

Abstract: Described are polypropylene molding compositions which have surprisingly good physical properties in combination with flame retardancy, which include copolymers represented by the formula: ##STR1## wherein n is >1, P is isotactic or syndiotactic polypropylene, and S is a grafted side chain having brominated monomeric units of the formula: ##STR2## wherein x=1 to 4, R.sub.1 is H or CH.sub.3, and R.sub.2 is H or a C.sub.1-4 lower alkyl group. Polymer blends including such graft copolymers and methods for making such flame retardant polymer compositions are also described.

Abstract: Flame retardant hot melt adhesives include atactic polypropylene having grafted thereon a ring-halogenated styrene. The compositions may also include homopolymers of the styrene monomer or equivalents, as well as non-halogenated atactic polypropylene. Tackifying agents, waxes, anti-oxidants and other additives may also be included.

Abstract: Halogenated unsymmetrical higher alkyl bisphenoxy alkanes having utility as non-blooming flame retardant agents.

Abstract: Flame retardant ABS compositions incorporate an effective amount of halogenated unsymmetrical higher alkyl bisphenoxy alkane and an enhancing agent.

Abstract: Flame retardant ABS compositions incorporate an effective amount of a polybrominated higher alkylbenzene or mixture thereof and an enhancing agent.

Abstract: Normally combustible thermoplastic polyolefins such as polystyrene and polypropylene may be flame retarded without discoloration utilizing a flame retardant additive mixture comprising hexabromocyclododecane and one or more bis-(polybromophenoxy)ethane.

Abstract: Novel flame retardant compositions, which are useful in the preparation of rigid polyurethane foams, comprise a sucrose polyol, an aromatic polyester polyol, and a brominated, hydroxyl-containing pentaerythritol.
