  • Patent number: 6894117
    Abstract: A substantially non-gelled polymeric composition is disclosed and comprises the reaction product of an A polymer which is an addition polymer having 3.5 or more reactive functional groups per polymer chain and a B polymer having about 2 to about 3 functional groups per polymer chain that are co-reactive with the reactive functional groups of the A polymer. Also disclosed is a process for preparing such polymeric compositions, powder coatings and 100% solids ink resins prepared with such polymeric compositions, and a method for deglossing a powder coating using such polymeric compositions.

  • Patent number: 6646091
    Abstract: Coating compositions include polymeric particles, an isocyanate-containing crosslinking agent, and water. The polymeric particles include at least one incorporated monoalkenyl aromatic monomer, at least one incorporated vinyl-containing surfactant macromonomer, and at least one incorporated acrylic monomer. At least one incorporated acrylic monomer in the polymeric particles includes a hydroxyl, amine, or a carboxylic acid functional group. The crosslinking agent is an isocyanate-containing organic compound or such a compound with blocked isocyanate groups. Coating compositions may be deposited and cured by heating to form crosslinked coating compositions. Such crosslinked coating compositions exhibit excellent solvent resistance.

  • Patent number: 6605681
    Abstract: A process is disclosed for a continuous, high temperature polymerization process for preparing a free radically polymerized epoxy-functional polymeric product. The process comprises continuously charging into a reactor at least one epoxy-functional acrylic monomer, and optionally at least one non-functional free radical polymerizable monomer. An optional free radical polymerization initiator may also be added. The reactor is maintained at an effective temperature for an effective period of time to cause polymerization of the monomers into a polymeric product, such that the polymeric product is formed substantially free of gel particles. A clear coating is also disclosed incorporating polymers of the present invention, such that the clear coating has a low Delta b value at standard conditions.

  • Patent number: 6552144
    Abstract: A process is disclosed for a continuous, high temperature polymerization process for preparing a gel free polymeric product. The process comprises continuously charging into a reactor at least one monomer such that the reactor is filled to 100 percent of its usable volume. The reactor is maintained at an effective temperature for an effective period of time to cause polymerization of the monomers into a polymeric product, such that the polymeric product is formed substantially free of gel particles.
