  • Patent number: 6420479
    Abstract: A colloid composition is presented which contains an amphiphilic star polymer having potentially crosslinkable sites on the polymer backbone. The potentially crosslinkable site is either a sterically hindered silane monomer or an acetoacetoxy-containing monomer. When the crosslinkable site is a sterically hindered silane monomer the star polymer also contains an internal catalyst, and when the crosslinkable site is an acetoacetoxy group the colliod composition also contains a non-polymeric polyfunctional amine. The star polymer can be either a random or heteroarm star polymer. The colloid composition is useful in the formation and stabilization of emulsion polymers, as a replacement for surfactants currently used for this purpose. Emulsion polymers formulated with the colloid composition are especially useful for one-part coatings such as paints and adhesives.

  • Patent number: 5719244
    Abstract: Latex binders are disclosed which are used to prepare freeze-thaw-stable latex coating compositions which may be free of volatile freeze-thaw/open-time additives. The latex binders are prepared by combining a polymer which is the polymerization product of a polymerizable saccharide monomer, an acrylic monomer and, optionally, a monomer selected from styrenic monomers, ionic monomer and wet adhesion monomers. The latex coating compositions are freeze-thaw stable, even in the total absence of a volatile freeze-thaw additive, and exhibit improved open-time when compared to a latex coating composition which does not contain a volatile freeze-thaw additive. Methods for preparing the freeze-thaw-stable latex coating compositions are also disclosed.
