  • Epoxy/acrylic terpolymer self-fixturing adhesive
    Patent number: 6521732
    Abstract: A (meth)acrylate terpolymer comprising 1-30% of total terpolymer weight epoxy-functional (meth)acrylate monomer units, 1-98% of total terpolymer weight tackifier (meth)acrylate monomer units, and 1-98% of total terpolymer weight compatibilizing (meth)acrylate monomer units, wherein the compatibilizing (meth)acrylate monomer unit is a (meth)acrylic ester derived from an aromatic alcohol containing 6-14 carbon atoms. Also provided are self-fixturing adhesive compositions comprising the acrylate terpolymer of the present invention and methods of their use.
    Type: Grant

  • Dendritic polymer dispersants for hydrophobic particles in water-based systems
    Patent number: 6518370
    Abstract: Dispersants that adsorb to hydrophobic particle surfaces in aqueous media are described. The dispersants comprise dendritic polymers having at least one ionizable moiety and at least one peripheral hydrophobic long chain hydrocarbon moiety. Dispersions and inks wherein the dispersant operates as a solitary or co-dispersant are also described.
