Will copolymenze with almost all vinyl monomers. Composition can be varied over wide limits. Examples: vinyl chloride, vinyl acetate, acrylonitrile, styrene, maleic anhydride, etc,



Permits control of hydrophobic andhydrophilic characteristics of product. Examples: 65% vinylpyrrolidone—35% vinyl acetate, soluble in water. 35% vinylpyrrolidone—65% vinyl

Products have been found of interest as fiber and resin modifiers, adhesives, textile sizing and finishing compounds, binders and emulsions-Example: A small percentage of vinylpyrroli­ done with acrylonitrile gives greaterhydrophilic character and improved dyeability and handle.
