摘要： An integral geogrid includes a plurality of interconnected, oriented strands having an array of openings therein that is produced from a coextruded multilayer polymer sheet starting material. By virtue of the construction, the coextruded multilayer sheet components provide a crystalline synergistic effect during extrusion and orientation of the integral geogrid, resulting in enhanced material properties that provide performance benefits to use of the integral geogrid in soil geosynthetic reinforcement.

摘要： A method for producing a phase difference film is provided. The phase difference film includes an orientation layer formed of a resin C having a negative intrinsic birefringence value. The resin C contains a block copolymer having a block (A) including as a main component a polymerization unit A having a negative intrinsic birefringence value and a block (B) including as a main component a polymerization unit B, and a weight fraction of the block (A) therein being 50% by weight or more and 90% by weight or less. The phase difference film has an NZ factor of greater than 0 and smaller than 1. The method comprising: forming a single layer film of the resin C; and causing phase separation of the resin C in the film, which includes a step of applying to the film a stress along a thickness direction thereof.

摘要： A strip-shape softened resin sheet (S) which is continuously extruded from a molten resin extruder is cut to a unit resin sheet and a press molded product is manufactured by press-molding the unit resin sheet in a press-molding machine 20. Prior to press-molding the unit resin sheet (U) by the press-molding machine, the unit resin sheet (U) is heated by a heating machine 16. The heating machine 16 comprises a first heating furnace 84 and a second heating furnace 86. The first heating furnace 84 includes a series of heaters 84-3 and 84-4 whose heat source is infrared ray in a far-infrared region and the second heating furnace 86 includes a series of heaters 86-3 and 86-4 whose heat source is the infrared ray in a middle-infrared region. In the first furnace 84, the unit resin sheet (U) is continuously conveyed with a low velocity and is gradually heated by the far-infrared ray up to temperature which is slightly lower than the temperature which is suitable for press-molding the unit resin sheet (U). In the second furnace 86, the unit resin sheet (U) is stopped and is rapidly heated by the middle-infrared ray. By efficiently heating the unit resin sheet (U), a cycle time can be shortened and the production speed can be improved.
