Bill E. Burgert 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).

  • Alloys of vinylidene chloride interpolymers and olefin polymers
    Patent number: 4950718
    Abstract: A compatibilized blend of at least three polymers is provided. One polymer is a vinylidene chloride interpolymer, such as a copolymer of vinylidene chloride and vinyl chloride. A second polymer is an olefin polymer, such as polyethylene. A third polymer is a compatibilizing polymer such as an ethylene/alkyl acrylate or an ethylene/alkyl methacrylate copolymer. The compatibilized blend, after melt processing, has mechanical properties which are better than those predicted by a straight line volume fraction relationship of the vinylidene chloride interpolymer and the olefin polymer.
