  • Patent number: 6787590
    Abstract: This invention relates to novel composites comprising plastic and plant material derived from members of Parthenium spp. and, in particular, Parthenium argentatum (also known as guayule), Parthenium tomentosum or Parthenium incanum. The invention is also directed to composites that possess insect, fungal, and microbial resistance. Products made from composites of the instant invention are useful to make numerous items, particularly those used for construction such as lumber, plywood, particleboard, fiberboard, poles, railroad crossties, or the like.

  • Patent number: 6395808
    Abstract: Provided is an additive for a thermoplastic resin prepared by mixing tannin with a coupling agent, and the above additive inhibits the thermoplastic resin from being reduced in a molecular weight in heating and melting and achieves heat stabilization of the thermoplastic resin. Accordingly, it becomes possible to recycle the molded articles.

  • Patent number: 5196460
    Abstract: A tackifier composition for use in rubber compounds is disclosed. The tackifier comprises a pure lignin with a water solubility of up to 1% by weight and a carbohydrate level of less than 50% by weight. In another embodiment of the invention, the pure lignin functions as both a tackifier and an antioxidant. In yet another preferred embodiment of the invention, the improved tackifier produces synergistic results when blended with a commercial tackifier, and the antioxidant likewise yields synergistic results when mixed with a commercial antioxidant.
