    摘要: A process for producing an oriented composite polyolefin resin film which comprises melt-laminating a polyolefin resin sheet for a paper-like layer on at least one surface of a monoaxially stretched polyolefin resin sheet for a substrate layer, and then stretching the resulting laminated sheet in a direction perpendicular to said monoaxially stretched direction. The polyolefin resin sheet for the substrate layer is a sheet of composite structure prepared by melt-extruding the specific compositions (A), (B), and (C) through a co-extrusion die in such a manner that a layer composed of the thermoplastic resin composition (A) is laminated on one surface of an intermediate layer composed of the polyolefin composition (B) containing a filler and a layer composed of the thermoplastic resin composition (C) is laminated on the other surface of the intermediate layer. Said polyolefin resin sheet for the paper-like layer is composed of a specific polyolefin composition (D) containing a filler.

    摘要: A stretched film having excellent printing and writing properties and mechanical strength is produced by stretching a film molded from a styrene-grafted polyolefin resin in at least one direction. The styrene-grafted polyolefin resin is produced by heating an aqueous suspension containing 100 parts by weight of polyolefin resin particles, from 10 to 400 parts by weight of a styrene monomer, and a free radical polymerization initiator in an amount of from 0.01 to 1 part by weight per 100 parts by weight of the styrene monomer.

    摘要: A superabrasive wire saw-wound structure includes a superabrasive wire saw (10) formed with an average diameter D and a reel (1). The superabrasive wire saw (10) includes a core wire (11), a bonding material (12) surrounding a surface of the core wire (11), and a plurality of superabrasive grains (13) bonded to the surface of the core wire (11) with the bonding material (12). The reel (1) includes a peripheral surface (2) having one end (3) and the other end (4). The superabrasive wire saw (10) which is to be unreeled successively toward a workpiece is wound around the peripheral surface (2) reciprocatingly between the one end (3) and the other end (4) to be multi-layered. A pitch P for winding the superabrasive wire saw (10) around the peripheral surface (2) between the one end (3) and the other end (4) satisfies a relation of D
