  • Furan reimpregnation resin
    Patent number: 4604432
    Abstract: There are disclosed polymers containing tungsten chemically bonded in the polymer chain. The polymers are obtained by reacting 2-furanacrylic acid or 2-furoic acid with the reaction product of tungsten carbonyl with pyrrolidine. These polymers are useful as multi-cycle reimpregnation resins.
    Type: Grant
    Filed: June 24, 1985
    Date of Patent: August 5, 1986
    Assignee: Hitco
    Inventor: P. Anthony Hinman

  • Reaction product of polyol and a metal carbonyl/pyrrolidine complex
    Patent number: 4496740
    Abstract: It is disclosed that the properties of epoxy resins may be improved by incorporating therein at least one metal selected from the group consisting of boron, molybdenum, rhenium, tungsten and zirconium. The selection of a particular metal atom for incorporation into the epoxy resin or a combination of these metals will depend on the specific resin properties desired.
