Process for preparing solvent-type acrylic pressure-sensitive adhesives

A resin used for magnetic recording media, comprising a vinyl chloride copolymer containing vinyl monomers with hydroxyl groups and vinyl monomers with quaternary ammonium salt groups as component units. The resin is made by a method which comprises polymerizing an organic solvent solution containing vinyl chloride, vinyl monomers with hydroxyl groups and vinyl monomers with quaternary ammonium salt groups in a reacting apparatus to thereby precipitate a vinyl chloride copolymer, the interior surface of said reacting apparatus, which comes into contact with said organic solvent solution being coated with a fluororesin.

A resin used for magnetic recording media, comprising a vinyl chloride copolymer containing vinyl monomers with hydroxyl groups and vinyl monomers with quaternary ammonium salt groups as component units. The resin is made by a method which comprises polymerizing an organic solvent solution containing vinyl chloride, vinyl monomers with hydroxyl groups and vinyl monomers with quanternary ammonium salt groups in a reacting apparatus to thereby precipitate a vinyl chloride copolymer, the interior surface of said reactin apparatus, which comes into contact with said organic solvent solution being coated with a fluororesin.
