<p>A treating agent for rubber-reinforcing glass fibers which improves various performances of a rubber product, especially oil resistance; a rubber-reinforcing cord made with the treating agent; and a rubber product with high oil resistance. The treating agent comprises a water-soluble resolcinol/formaldehyde condensate and a soap-free acrylonitrile/butadiene copolymer latex. The term 'soap-free' means that the latex is one obtained through polymerization using a polymerization initiator such as potassium persulfate and either a reactive emulsifying agent, such as a styrenesulfonic acid salt or an acrylic or allyl compound, or a hydrophilic comonomer, such as a water-soluble polymer, a water-soluble oligomer, or acrylic acid, in place of a conventional emulsifying agent or surfactant.</p> |
