  • Patent number: 4808656
    Abstract: A curable high solids coating composition containing a reactive acrylic polymer formed from polymerizing an alpha, beta-ethylenically unsaturated monomer containing a functional group such as a hydroxyl group and other non-functional alpha, beta-ethylenically unsaturated monomers is disclosed. The polymer is prepared by organic solution polymerization techniques in an organic solvent and in the presence of t-amylperoxy compound and a 2,4-diaryl-1-alkene. The coating compositions are particularly useful as coatings for automobiles where they can be deposited as non-yellowing clear coats.

  • Patent number: 4789694
    Abstract: The paint coating composition comprises a cationic free, functional emulsion polymer mixture adapted to be coreacted at room temperature with glycoluril to provide a cured thermoset paint film. The process comprises copolymerizing ethylenically unsaturated monomers, including functional monomers, but excluding amine monomers, in an aqueous polymerization medium, followed by ion exchange of the resulting reactive emulsion polymer. Preferably, the glycoluril is processed through an ion exchange step separately or in conjunction with the reactive emulsion polymer. The resulting polymers are useful as binders in ambient cure surface coating application.
