  • Publication number: 20230053997
    Abstract: A method for manufacturing a fiber-containing sheet. In extruding resin into sheet form using a T-die, the extrusion from the T-die is performed with a first resin for forming a core layer and a second resin for forming both skin layers on both sides of the core layer laminated together. The first resin contains fiber material and the second resin does not contain fiber material.

  • Publication number: 20100283177
    Abstract: There is provided a process for producing a precursor film for a polypropylene-based resin retardation film that can yield films with almost no orientation and with high transparency. The process for producing a precursor film for a polypropylene-based resin retardation film comprises a step of pressing a molten sheet formed by extruding a molten polypropylene-based resin from a T-shaped die 12 at 180° C. or higher and 300° C. or lower between a cooling roll 16 having a surface temperature regulated to ?5° C. or higher and 30° C. or lower and a touch roll 14 having a surface temperature regulated to 80° C. or higher and 150° C. or lower, whereby the molten sheet is cooled and solidified.

  • Patent number: 4548983
    Abstract: A method for the manufacture of shaped article of hydrogel is provided. This shaped article of hydrogel is obtained by the polymerization in a mold of a mixture comprising:A. an alkylene glycol mono(meth)acrylate or a monomer mixture consisting preponderantly of an alkylene glycol mono(meth)acrylate,B. a polymer synthesized from a component A and possessing a polymerizable double bond in the molecular unit thereof,C. a water-soluble dipolar aprotic solvent, andD. at least one member selected from the group consisting of (a) water-soluble organic acids, (b) surface active agents, and (c) water-soluble organic substances which are poor solvents or non-solvents of the component B, and having the weight ratio of the component A to the component B in the range of 45:55 to 20:80.
