Abstract
Novel vinyl chloride copolymers including a hydroxyalkyl acrylate or metacrylate or allyl alcohol, an acid functionality from carboxylic acid-containing monomers and optionally an epoxy-containing vinyl monomer in selected proportions provide suitable binder resins for applications such as magnetic recording media, imparting enhanced dispersion and magnetic property characteristics while also having desirable rheological characteristics and, when the epoxy-containing vinyl monomer is used, desirable thermal stability.
