  • Publication number: 20180072910
    Abstract: A water-based, low-emission latex paint formulation includes a vinyl acetate/ethylene (VAE) latex including a VAE resin with from 80 to 95 weight % vinyl acetate residue and from 5 to 20 weight % ethylene residue, optionally including additional monomers as well as a pigment composition including inorganic solids selected from inorganic pigments, inorganic fillers and mixtures thereof present in an amount such that the paint formulation has a pigment volume concentration (PVC) of from 25% to 85%. The formulations are suitable for eggshell and flat latex paints and exhibit surprising durability.

  • Publication number: 20170029544
    Abstract: The present invention relates to a process for the emulsion polymerization of free-radically polymerizable, ethylenically unsaturated main monomers, and optionally further auxiliary monomers copolymerizable therewith, wherein the polymerization comprises a polymerization reaction phase starting with the first addition of an initiator or starting with the first addition of monomers, whatever is later, and ending with the completion of the addition of the initiator or the completion of the addition of total monomers, whatever is later, wherein the reaction temperature is increased during said polymerization reaction phase from a start temperature in the range of about 30° C. to about 85° C. to an end temperature in the range of about 60° C. to about 160° C., and wherein the polymerization temperature is increased for at least 25% of the duration of said polymerization reaction phase.

  • Publication number: 20150247053
    Abstract: 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.

  • Patent number: 9006329
    Abstract: An aqueous dispersion of a vinyl ester/ethylene copolymer is prepared by emulsion copolymerization of a monomer mixture comprising a vinyl ester, ethylene and a polyvinyl alcohol stabilizing system consisting essentially of (a) about 0.5 to about 3 wt. % based on the total monomer weight of a first polyvinyl alcohol having a degree of hydrolysis of at least 98 mole % and (b) about 1 to about 4 wt. % based on the total monomer weight of a second polyvinyl alcohol having a degree of hydrolysis of about 85 to about 90 mole % and a weight average molecular weight of at least 85,000 g/mol.
