m VINYLPYRROLIDONE for improvement of glass fiber laminating resins and copolymer systems GLASS FIBER LAMINATES Vinylpyrrolidone increases both wet and dry flexural strength of glass fiber laminates—the degree of improve­ ment depending on the catalyst and resin systems and the method of fabrication. COPOLYMER SYSTEMS Vinylpyrrolidone copolymerizes readily with styrene, maieic anhydride, acrylonitrile, acrylates, vinyl chloride, vinyl acetate and other vinyl monomers. Vinylpyrrolidone also

If you make regular or pressure sensitive adhesives, print­ ing inks, synthetic fibers, emulsion paints or glass fiber laminating resins, or work with copolymerization systems, send for technical information about Vinylpyrrolidone.
