Patents by Inventor Anthony F. Dean, Jr.

Anthony F. Dean, Jr. 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).

  • Multilayer thermoformable structure
    Patent number: 5385781
    Abstract: This invention relates to a multilayer thermoformable structure comprising (A) at least one cap layer and (B) at least one core layer, and polymer compositions for making the same. The multilayer structures and polymer compositions of the invention are useful in preparing thermoformed articles and are particularly useful in preparing liners for refrigerators and freezers. The multilayer structures and the polymer composition have good thermoformability and chemical resistance. The multilayer structures and the polymer composition have good surface properties including a glossy finish. Further these materials are compatible with new blowing agents, such as the hydrochlorofluorocarbons and hydrofluorocarbon blowing agents, which are more environmentally friendly. The layers of the multilayer structure do not require a glue layer.
    Type: Grant
    Filed: September 20, 1993
    Date of Patent: January 31, 1995
    Assignee: Ferro Corporation
    Inventors: Deenadayalu Chundury, Anthony S. Scheibelhoffer, Berdine L. Leonard, Ronald E. Thompson, Randall S. McAllister, Surachai Wimolkiatisak, Anthony F. Dean, Jr.
  • Composites and polymer compositions for making the same
    Patent number: 5374680
    Abstract: A polymer blend composition consisting essentially of:(i) at least about 55% by weight polystyrene,(ii) from about 1% to about 45% by weight of a selectively hydrogenated block copolymer of conjugated dienes and vinyl aromatic monomers which has been grafted with a carboxylic reagent, wherein the block copolymer contains up to about 50% by weight bound vinyl aromatic monomer, and(iii) from about 0.3% to 45% by weight of at least one block polymer of a vinyl aromatic monomer and conjugated diene, wherein the block polymer contains greater than about 60% by weight bound vinyl aromatic monomer.The polymer composition is useful in preparing multilayer thermoformable structures and articles comprising (A) at least one cap layer and (B) at least one core layer, such as liners for refrigerators and freezers. The multilayer structures and polymer composition have good thermoformability, chemical resistance and surface properties including a glossy finish.
