Patents by Inventor Robert G. Freelin

Robert G. Freelin 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 elastomers
    Patent number: 5783302
    Abstract: TPE's which comprise A blocks or B blocks or both A blocks and B blocks, which are crystalline and in which at least a part of the crystallinity result from the presence of crystallizable side chains. Such crystalline blocks are referred to as SCC blocks. TPE's containing SCC A blocks are novel and as such form part of the present invention. The invention also includes processes, compositions, shaped articles and assemblies which make use of TPE's containing SCC A blocks.
    Type: Grant

  • Thermoplastic Elastomers
    Patent number: 5665822
    Abstract: Thermoplastic elastomers (TPEs) containing side chain crystalline (SCC) blocks. The SCC blocks my be hard (A) blocks or the soft (B) blocks (or both) in the TPE. Some of these TPEs are novel, e.g. those in which A blocks are SCC blocks, and the B blocks are polyethers, polyacrylates, polyamides, polyurethanes or polysiloxanes. The SCC-containing TPEs are particularly useful as matrix materials for other components which are dispersed therein, e.g. energetic solids and other thermally responsive materials.
