More Information
Summary:Disclosed are aqueous polymer dispersions which can be used as binders in paper coating compositions. Such dispersions are made using a continuous polymerization process involving a tubular reactor with a continuous loop section and a secondary line section and comprise a polymer of polymerized copolymers (a) a vinyl ester, (b) an ethylenically unsaturated mono or di-carboxylic acid or half ester of a di-carboxylic acid, and (c) a comonomer having a multifunctional moiety.
