    摘要: An epoxy resin composition for forming prepregs is disclosed which includes an epoxy resin having at least two epoxy groups, a latent curing agent for the epoxy resin in an amount of 0.5-3.0 equivalents per equivalent of the epoxy groups of the epoxy resin, and a reactive, viscosity-increasing agent in an amount of 0.2-3.0 parts by weight per 100 parts by weight of the epoxy resin. The epoxy resin composition has an initial viscosity n.sub.I(50) at 50.degree. C. of 1,000-200,000 cP and an initial viscosity n.sub.I(23) at 23.degree. C. of at least 10,000 cP.

    摘要: An aqueous alkaline dispersion of a rubbery vinyl pyridine copolymer, trimethylol phenol, and a resorcinol compound, in certain amounts is useful in forming an adhesive for bonding polyamide or nylon cords to rubber compounds or stocks. After dipping the cord in the adhesive dip, the coated cord is heated to dry it and heat cure or heat set the adhesive on the cord. Thereafter, the adhesive containing cord is combined or laminated (calendered) with a curable rubber compound and the resulting assembly is cured. High H-adhesions are obtained with this one-step or single treatment coating dip. It is particularly useful for bonding crystalline polyamides having a large number of aromatic groups in the polymeric structure, e.g., "Fiber B."

    摘要: Solid curable polyester resin compositions comprising a filler or fibrous reinforcements impregnated with a solid solution of a crystalline polyester and crosslinking agent therefor are prepared by:A. mixing a liquid crosslinking agent with a solid crystalline polyester which is insoluble in said crosslinking agent at room temperature;B. heating the mixture of said solid crystalline polyester and liquid crosslinking agent to a temperature at which said polyester dissolves in said crosslinking agent and a temperature which is below that at which the polyester and crosslinking agent cure;C. forming a solid solution of said polyester and crosslinking agent by cooling the heated mixture thereof; andD. mixing with the polyester and crosslinking agent prior to the formation of said solid solution one or more of a filler, fibrous reinforcements or amorphous polyester.
