Textile reinforced elastomeric composites having a textile reinforcement embedded in an elastomeric matrix. The textile reinforcement includes fibers or yarns and an adhesive treatment applied to the fibers wherein the adhesive treatment comprises graphene or graphene oxide. The textile reinforcement may be a fabric or a tensile cord. The fibers may be polyester, aramid, carbon fiber, glass fiber, PBO, PEN, or polyamide. The adhesive treatment may be an epoxy treatment, an epoxy-latex treatment, an acrylic polymer treatment, a latex treatment, a polyurethane treatment, an RFL treatment, a rubber cement, or combinations thereof. The composite may be in the form of a toothed belt wherein the textile reinforcement is a tooth cover or a helically wound tensile cord embedded in the belt.

The present invention provides a UV curable resin composition that can be cured without going through a high-temperature heating process and has excellent adhesiveness, and a sheet using the same.

The UV curable resin composition comprises a rubber component with a diene skeleton, a photopolymerization initiator, a crosslinker and a tackifier. The composition contains a solid rubber component and a liquid rubber component at 25° C. as the rubber component with the diene. Since the UV curable composition can be cured by UV irradiation in a short time, it can be applied not only to adherends with high heat resistance but also to various parts.

An adhesive composition is provided and includes the following components (A) to (D): (A) a radically polymerizable compound; (B) (B-1) a polymer consisting of at least one repeat unit derived from a polymerizable compound of formula (I), or (B-2) a polymer consisting of at least one repeat unit derived from a polymerizable compound of formula (I), and at least one repeat unit derived from another radically polymerizable compound; (C) a polymerization initiator; and (D) a reducing agent.

The present invention relates to an aqueous emulsion including an ethylenically unsaturated monomer unit-containing polymer as a dispersoid and a polyvinyl alcohol as a dispersant. The content of a free polyvinyl alcohol in the aqueous emulsion is 0.2 to 20 parts by mass relative to 100 parts by mass of the ethylenically unsaturated monomer unit-containing polymer. The free polyvinyl alcohol has a degree of saponification of 80.0 to 99.5 mol % and a viscosity-average degree of polymerization of 200 to 5000, and the free polyvinyl alcohol has a symmetry factor (W.sub.0.05h/2f) that satisfies the following expression (1) as determined by gradient high-performance liquid chromatography for reversed-phase separation using a water-acetone eluent according to JIS K 0124 (2011).
