James G. Bennett 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).
Abstract: A novel process is provided for preparing a blend of rubber, a polyphenylene ether resin and an alkenyl aromatic addition polymer which comprises using an alkenyl aromatic monomer as a solvent for the oxidative coupling of a phenol to a polyphenylene ether resin and thereafter adding a rubber and polymerizing the mixture to form said blend of rubber, an alkenyl aromatic addition polymer and a polyphenylene ether resin.

Abstract: An improved process is disclosed for preparing polyphenylene ethers in which a polyamine complexing agent is employed to terminate the oxidative coupling reaction and to remove the metal component of the catalyst from the polymer.
Abstract: An improved process is disclosed for preparing polyphenylene ethers in which a complexing agent selected from the group consisting of biguanide, di-o-tolylbiguanide, dicyanodiamide, and L-Arginine is employed to terminate the oxidative coupling reaction and facilitate the recovery of the polymer.
Abstract: An improved process is provided for preparing polyphenylene ethers by oxidatively coupling a di-ortho substituted phenolic precursor in a reaction system containing oxygen at a pressure of more than one atmosphere, and a complex catalyst formed from a cupric halide and a primary or secondary amine catalyst.
Abstract: There is disclosed herein an improved process for the preparation of high molecular weight polyphenylene ethers by oxidatively coupling a di-ortho substituted phenolic precursor in a reaction vessel containing oxygen and a complex catalyst formed from a copper salt and either a primary, secondary or tertiary amine wherein in the presence of an aqueous phase a quaternary ammonium salt is employed to promote the rate of reaction.
Abstract: Amorphous polyphenylne oxide resins and polyphenylene oxide resins with lower degrees of crystallinity are prepared by adding a solution thereof to an antisolvent. The resins have from about 0 to 75 percent of the crystallinity of conventional polyphenylene oxide resins and provide compositions, e.g., with styrene resins, having maximum physical properties after a single extrusion.
