Abstract
Novel phosphorylated compositions of a vinyl chloride copolymer or terpolymer, a phenoxy resin, a hydroxyalkyl acrylate or methacrylatelactone adduct or a reaction product of a normally solid pendant-hydroxyl-containing thermoplastic polymer having at least 8 hydroxyl groups per molecular chain and an adduct which is the product of either a hydroxylalkyl acrylate or methacrylate or a lactone-acrylate adduct and an organic diisocyanate having improved dispersion characteristics suitable for use in applications such as magnetic recording media.
