M*CH* V-Pyrol monomer—an extremely versatile product that opens the door to literally hundreds of new and exciting polymerizations.

Uncommon—because V-Pyrol® N-vinyl-2-pyrrolidone in­ ternally modifies polymers, adding many of the unusual properties of an equally un­ common homopolymer— PVP (polyvinylpyrrolidone). Imagine making acrylonitrile or PVC copolymers with greater dye receptivity. Vinyl acetates and acrylics with fantastic ad­ hesion to glass. Making PVC and poly­ styrene polymers more re­ sistant to heat. Or adding other desir­ able properties such as water solubility, strength, hardness, stiffness and grease resistance. And you can effec­ tively modify a polymer's melting point, surface activ­ ity, dielectric properties or water-swelling equilibrium. The degree to which you can modify polymers de­ pends largely on the ratio of the various comonomers.

And V-Pyrol is readily copolymerized with an al­ most unlimited number of comonomers—in virtually any proportions and under a wide variety of conditions. Send for literature and a sample: We've com­ piled a 24-page technical brochure on V-Pyrol which gives detailed information on copolymerizations with each of the above mono­ mers, discusses reaction ra­ tios vs. performance, and gives a summary of terpolymers and graft copolymers based on V-Pyrol. Also, the usual data on physical prop­ erties and availability. Just fill out and mail the coupon.
