Abstract: A coated metal pipe which comprises a pipe coated with a composition comprising2 to 40 wt. parts of low molecular weight oxidized polymer of polypropylene or propylene-ethylene copolymer;5 to 40 wt. parts of a rubber component selected from a group consisting of styrene-butadiene copolymer, polyisoprene, butyl rubber, chlorosulfonic polyethylene and polyisobutylene;5 to 50 wt. parts of a tackifier and 10 to 80 wt. parts of asphalt.

Abstract: A heat printing sheet having a pattern of a hot melt ink composition on a base, the improvement comprising using a hot melt ink composition which comprises 5-60 wt. parts of a base polymer of ethylene-vinyl acetate copolymer having 5-50 wt. % of the vinyl acetate content and 4-1000 g/10 min. of a melt index or a mixture of said ethylene-vinyl acetate substituted with 10-60 wt. % of the other polymer; and 20-80 wt. parts of a tackifier selected from terpene resins, hydrogenated dicyclopentadiene resins, lower styrene resins, rosins, rosin polyol esters, hydrogenated rosin and rosin polyol esters and alicyclic hydrocarbon resins and 0.1-30 wt. parts of a pigment or dye, and the hot melt ink composition is melted at 80.degree.-250.degree. C and is coated on an engraved roll and is instantaneously printed on a base of synthetic polymer film having 10-100 of a thickness and smooth surface under 0.5-10 Kg/cm.sup.2 (gauge) to form the pattern of the hot melt ink composition having 10-3000 of a thickness.

Abstract: A chromatography solid support which is prepared by immersing a microporous inorganic substrate in a radiation-polymerizable monomer and subjecting said monomer to high energy radiation to produce a radiation-induced polymerization of the polymerizable monomer is disclosed.

Abstract: The present invention is concerned with a method and apparatus which blend components of a thermoplastic resin composition in an extruder having a cylindrical body, a screw, and a heating means, wherein the cylindrical body has a large bore part, a tapered part, and a small bore part, and the screw has a large diameter flight, a tapered flight, and a small diameter flight which is fitted within the cylindrical body. The tapered flight has free pass recesses, if desirable, and the roughness of the inner surface of the cylindrical body and/or roughness of the outer surface of the flight of screw are decreased as one proceeds in the direction from the small bore part to the outlet.

Abstract: A coated metal pipe which comprises a pipe coated with a composition comprising 5-30 wt parts of ethylene-vinylacetate copolymer having a vinylacetate content of 15-40 wt% and a melt index of 1-1,000 g/10 min; 2-20 wt parts of low molecular weight oxidized polymer of polypropylene or propylene-ethylene copolymer; 5-40 wt parts of styrene butadiene copolymer; 5-50 wt parts of a tackifier and 10-80 wt parts of asphalt.

Abstract: Substrates are bonded by applying to a substrate a graft copolymer of 0.1 - 20 parts by weight of an unsaturated carboxylic acid or anhydride, 1 - 40 parts by weight of a vinyl monomer containing at least one chlorine atom in the presence of 99 - 40 parts by weight of an ethylene-vinylacetate copolymer.
