Abstract: Provided are: a stretched film having excellent heat resistance, dimensional stability, mechanical properties, and adhesiveness; and a method for producing a stretched film. The present invention relates to: a stretched film containing acrylic rubber particles and an acrylic resin having a glass transition temperature of 120° C. or higher, the stretched film being characterized by having a shrinkage rate of 1.5% or less when left standing at 85° C. and 85% RH for 120 hours, and having an endurable number of cycles, by MIT flex test, of 350 times or more; and a method for producing a stretched film.

Abstract: Disclosed is an elastic roller for electrophotography wherein bleeding of an unreacted material, a plasticizer and an additive from the elastic layer to the roller surface is suppressed. Also disclosed is an elastic roller for electrophotography having excellent durability for long use. Specifically disclosed is (1) an elastic roller for electrophotography comprising a metal supporting member, an elastic layer formed on the outer circumferential surface of the metal supporting member, and a coating film which is formed on the elastic layer using a styrene-based thermoplastic elastomer and/or an olefin-based thermoplastic elastomer and composed of at least one or more layers.

Abstract: The technique of preparing a semiconductive rubber by adding a conductivity imparting agent to resin matrix is so general but controlling the exhibiting conductive properties to a semiconductive range is difficult and in the technique of imparting conductivity by using an electronic conductive agent such as carbon black, uniform dispersion within the system is difficult and this often causes the problems of the sample fluctuation of the electric properties and voltage dependency of the obtained semiconductive rubber. The semiconductive resin composition of the present invention comprises (A) an oxyalkylene polymer having at least one hydrosilylizable alkenyl group in each molecule, (B) a compound having at least two hydrosilyl groups in each molecule, (C) a hydrosilylizing catalyst, and (D) an ionic conductivity imparting agent or (E) a nonionic surfactant.
