Abstract: Polyolefin resin composition having an excellent resistance to blushing on impact, excellent gloss, high impact resistance and high stiffness, which comprises a specific ethylene/propylene block copolymer (A) consisting essentially of first and second segments of an ethylene/propylene copolymer having each a specific ethylene content and a copolymer of ethylene (B) selected from a specific polyethylene and a specific copolymer of ethylene and an .alpha.-olefin having 3 or more carbon atoms. The resin composition is useful for the production of molded products having excellent properties.

Abstract: 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.

Abstract: A coating material obtained by incorporating into a paper coating material pullulan, which is a linear high polymer having repetition units, bonded through .alpha.-1,6 linkages, of maltotriose, a trimer of glucose, and is represented by the formula, ##SPC1##Wherein n represents the polymerization degree and is an integer of 20 to 10,000, is excellent in such properties as gloss, printing gloss, adhesive strength, and viscosity stability during storage.
