Bryce W. Steinmetz 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).

  • Thermoplastic polyurethanes with crystalline chain ends
    Patent number: 9546242
    Abstract: The present invention relates to novel thermoplastic polyurethane (TPU) compositions that have crystalline chain ends. The TPU compositions of the invention can provide improved resiliency, lower surface free energy, and/or reduced stickiness, while maintaining other desirable physical properties. The present invention also provides the described TPU compositions that are further grafted with vinyl alkoxysilane moieties allowing for crosslinked networks of the TPU compositions. The present invention also provides plasticizer-free, very soft TPU compositions without the processing difficulties often associated with such materials. The invention further provides means of reducing the surface tension of a TPU composition which can allow for improved blend compositions, and means of crosslinking the described TPU compositions.

  • Melt processable copolyetheramide elastomers
    Patent number: 8722794
    Abstract: The present invention relates to a melt processable copolyetheramide made by reacting (a) one or more segments of polyamide hard blocks derived from a lactam-terminated diisocyanate and a lactam monomer, and (b) one or more segments of polyether soft blocks derived from a polyether diol. The invention further provides for methods of making said copolyetheramide, including a continuous extruder method of production.
