    摘要: A molded article, particularly for optical use, formed of a thermoplastic saturated norbornene-based polymer composition including a thermoplastic saturated norbornene-based polymer excellent in heat resistance, etc., and a filler, the composition being capable of preventing cracks even when an insertion part having a linear expansion coefficient greatly different from that of the polymer is present and a thermal change occurs. The filler is selected from a fibrous filler and a combination of a fibrous filler with a powdery filler.

    摘要: A composition including a thermoplastic saturated norbornene group polymer and a partially etherified product of a polyhydric alcohol having at least 3 hydroxyl groups incorporated thereinto. The composition exhibits excellent adhesion to the recording film of an optical disk and adhesion to a hard coating film or a protective film formed by coating an acrylic ultraviolet curing coating material or like films without deteriorating the excellent heat resistance and transparency inherent to thermoplastic saturated norbornene group polymers. An optical disk substrate formed of this composition and an optical disk including the optical disk substrate and an information recording film and/or a light reflecting film and a protective film laminated thereon are also disclaimed.

    摘要: A phase plate comprises, as a birefringent layer, a film obtained by stretching and orienting a sheet of a thermoplastic saturated norbornene resin, which has been formed by melt forming. The phase plate of the invention is such that the birefringent layer is optically even at the whole surface, and such optical evenness remains constant even by changes of temperature, humidity and/or the like. The phase plate of the invention can be used in parts for polarization microscopes, parts for liquid crystal displays, etc., and is particularly suitable for use in a phase plate for liquid crystal displays.
