Abstract: Provided is a method for producing a shaping material that contains a cyclic olefin polymer and has a low content of a volatile impurity. This method for producing a shaping material is a method which includes passing a raw-material resin in a molten state through an extruder to produce a shaping material, and in which the extruder is equipped with a cylinder, a screw housed within the cylinder, a resin introduction port for introducing the raw-material resin into the cylinder, a resin discharge port for discharging the molten resin from the cylinder, a fluid injection port for injecting carbon dioxide or water into the cylinder between the resin introduction port and the resin discharge port, and a fluid discharge port for removing fluid in the cylinder by suction downstream of the fluid injection port and between the resin introduction port and the resin discharge port.

Abstract: Provided is a resin film having excellent size stability in a high-temperature environment. A resin film formed of a resin containing an alicyclic structure-containing polymer having crystallizability, wherein an absolute value of a thermal size change ratio when the film is heated at 150° C. for 1 hour is 1% or less in any in-plane direction of the film. The alicyclic structure-containing polymer may preferably be a hydrogenated product of a ring-opened polymer of dicyclopentadiene. Also provided is a method for producing the resin film including a step of relaxing strain of the crystallized film while the crystallized. film is kept flat.

Abstract: Provided is a resin that can simultaneously achieve a high refractive index, high heat resistance, and low birefringence. A hydrogenated cycloolefin copolymer is obtained through hydrogenation of a cycloolefin copolymer that includes a structural unit derived from 1-naphthylnorbornene and a structural unit derived from 2-naphthylnorbornene, wherein an average endo isomer ratio of the 1-naphthylnorbornene and the 2-naphthylnorbornene is 50 mol % or more. The hydrogenated cycloolefin copolymer is suitable for use as a material of an optical element such as an optical lens.

Abstract: The present invention is a method for producing a stretched film comprising stretching an unstretched film that is formed using a hydrogenated dicyclopentadiene ring-opening polymer at a temperature of 95 to 135° C. and a stretching ratio of 1.2 to 10, followed by heating at a temperature of 150 to 220° C. Since the thus-obtained stretched film has excellent transparency and low coefficient of linear expansion, the stretched film is suitable for not only use in optical applications but also use for electronic materials.
