摘要： PROBLEM TO BE SOLVED: To obtain a light-scattering sheet which imparts diffusibility and directivity to reflection light by forming the sheet of a sea polymer and an island polymer having a refractive index different from that of the sea polymer by a specified value, and by bringing the particle size of the island polymer, the wt. ratio of sea polymer to island polymer, and the sheet thickness each into a specified range. SOLUTION: The sheet is formed of a sea polymer and an island polymer having a refractive index different from that of the sea polymer by 0.01-0.08. The average particle size of the island polymer is 0.5-10 μm; the wt. ratio of sea polymer/island polymer is (70/30)-(40/60); and the sheet thickness is 5-200 μm. A thermoplastic polymer is suitable as the sea polymer, and a resin having a refractive index different from that of the sea polymer is suitably selected and used as the island polymer. The average particle density of the island polymer is adjusted to about 1-100 (1010/cm3). The use of such a sheet enable scattered light to be directed usually in a range of diffusion angle of 5-50 deg..

摘要： PROBLEM TO BE SOLVED: To manufacture a styrene resin foam having a fine and uniform bubble-structure using an incombustible volatile foaming agent harmless to the environment. SOLUTION: A manufacturing method is comprised of injecting and mixing a volatile foaming agent (e.g. 1,1,1,2-tetrafluoroethane, etc.), into a melted styrene resin at a pressure not less than 30 MPa (e.g. about 30-45 MPa) followed by foaming with extruding the melted mixture. The preparation method otherwise may foam either with extruding the pressurized melted mixture under a pressure at 15-30 MPa or with extruding the melted mixture under an atmospheric pressure. The amount of the volatile foaming agent used may be about 0.1-30 pts.wt. to 100 pts.wt. of the styrene resin.
