Dahlia Haynes 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).

  • Copolymers from lactide
    Patent number: 7754826
    Abstract: Disclosed is a process for producing lactide-based copolymers and copolymers produced by the process. The copolymers are formed by the copolymerization of a lactide monomer with a secondary material. In one embodiment, the secondary material can be derived from renewable resources, providing a product copolymer completely derived from renewable resources. The disclosed materials may display improved hydrolytic and thermal characteristics as compared to previously known lactide-based materials. Exemplary secondary materials that can be copolymerized with lactide can include polyhydroxy alkanoates, long chain primary alcohols, and depsipeptides.

  • Fluorinated lactide-based copolymers
    Patent number: 7695795
    Abstract: Disclosed is a process for producing lactide-based copolymers and the copolymers produced by this process. Disclosed copolymers are formed in one embodiment through the copolymerization of a lactide monomer with a fluorinated diol, for example a perfluorinated polyether monomer, oligomer or copolymer. The disclosed materials may display improved mechanical characteristics, hydrolytic characteristics, and thermal characteristics as compared to previously known lactide-based materials.
