A power transmission belt (B) has a reinforcing fabric (13) covering a pulley contact surface thereof. A cover layer (15) adheres to the reinforcing fabric (13) to cover surfaces of fibers or yarns constituting the reinforcing fabric (13), and is exposed outside. The cover layer (15) contains crosslinked polyolefin particles (16) in which polyolefin molecules are crosslinked with each other.

A joined body of a resin body containing a fluorine-based resin and a rubber body containing a vulcanized silicone rubber. It is preferable that the vulcanized silicone rubber contains a dimethylsiloxane unit. It is found that, by performing predetermined plasma treatment on the surface of a rubber body containing a vulcanized silicone rubber, the rubber body adheres to a resin body containing a fluorine-based resin.

The present invention relates to a double-sided adhesive tape used for applications including the attachment of front glass for mobile devices. A core layer of the double-sided adhesive tape is prepared by adding an acrylic elastomer free of carbon-carbon double bonds while being highly miscible with an acrylic resin to an acrylic monomer(s) and performing curing, and thus can improve the impact resistance of the final double-sided adhesive tape. Also, the core layer may take a form of foam due to the introduced filler such as glass bubbles or organic microspheres, and thus can further contribute to improving the impact resistance of the final double-sided adhesive tape.

To provide a process for producing a film excellent in water vapor barrier property, tensile elongations and transparency.

A resin material containing polychlorotrifluoroethylene (PCTFE) is melted and extruded into a film from an extrusion die, the extruded product is brought into contact with a cooling roll having a surface temperature of at most 120 C. in a state such that the surface temperature of the extruded product is higher than the crystallization temperature of PCTFE to form a film web, and the film web is subjected to heat treatment at from 80 to 200 C. to obtain a film.
