John D. Kraan has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Automotive coatings from non-aqueous dispersions
    Patent number: 6344502
    Abstract: A non-aqueous dispersion of a polymer in a non-polar hydrocarbon. The polymer is produced by a free-radical addition polymerization reaction of a group of monomers including at least one polar monomer and at least one amine-functional monomer which takes place in the presence of an alkyd resin.
    Type: Grant

    Assignee: The Sherwin-Williams Company
    Inventors: John R. Babjak, Liza A. Capino, John D. Kraan, Mohamad D. Shalati, Susan L. Smith, Demetri L. Vallion, Richard S. Valpey, III, Thomas W. Yokoyama
  • Non-aqueous dispersions
    Patent number: 6051633
    Abstract: This invention relates to high solids, low VOC, low viscosity, filterable, non-gritty non-aqueous dispersions, and coating compositions containing said non-aqueous dispersions.

  • Curable compositions incorporating anhydride-functional polymers derived from alkenyl succinic anhydride
    Patent number: 5589560
    Abstract: A curable composition which comprises:(a) an anhydride-functional polymer obtained by polymerizing under free radical addition polymerization conditions, a monomer mixture comprising:(i) 20 to 75 weight percent of an alkenyl succinic anhydride having the structure: ##STR1## wherein R.sub.1, R.sub.2 and R.sub.3 are each independently hydrogen or alkyl or substituted alkyl of 1 to about 30 carbons; and(ii) 25 to 80 weight percent of at least one (meth)acrylic monomer copolymerizable with the alkenyl succinic anhydride; and, optionally,(iii) 0 to 75 weight percent of at least one unsaturated monomer, other than a (meth)acrylic monomer, which is copolymerizable with the anhydride and the (meth)acrylic monomer; and(b) a compound having an average of at least two functional groups per molecule which are reactive with anhydride groups.
