Resin compositions excellent in both flame retardation and weather durability, comprising (1) a styrene resin, (2) a halogen-containing flame retarder such as decabromodiphenyl ether and (3) an inorganic hydrate compound such as diatomaceous earth or a magnesium compound such as magnesium hydroxide and oxide.

Flame retardant polymer composition

A rubber-modified polystyrene resin composition consisting essentially of a rubber-modified polystyrene and a transparent, resinous styrene-butadiene block copolymer containing 65 to 95% by weight of styrene and 5 to 35% by weight of butadiene. This resin composition is excellent in impact strength, elongation, flexural stress clouding, hinging endurance, and surface gloss.

Rubber-modified polystyrene resin composition

A novel thermoplastic resin composition consisting essentially of polystyrene and a styrene-butadiene block copolymer. This resin composition is transparent, is excellent in mechanical properties, particularly in elongation, impact strength, and stiffness, is not liable to become cloudy on being bent, and is favorable in hinging endurance as well as in thermal resistance.

Thermoplastic resin composition

A resin composition consisting essentially of a styrene-butadiene block copolymer resin, a liquid polybutadiene resin or its modification product, and a tackifier. This resin composition is transparent, excellent in mechanical properties, particularly elongation, impact strength and elastic recovery, and is also improved in film-forming ability and tackiness.
