  • Patent number: 5221579
    Abstract: A processable thermoplastic conductive composite resin is formed by coating polypyrrole onto the surface of microbeads by in situ oxidative polymerization. The microbeads, generally having an average diameter from about 0.5 to about 500 microns, are coated with polypyrrole by combining pyrrole, oxidizing agent and the beads in a protic solvent such as water, methanol, ethanol, ethylene glycol and the like. The pyrrole polymerizes on the surface of the microbeads. The microbeads, which are thermoplastic, can then be processed and the conductivity of the processed polymer remains high, generally about 0.1 to about 10 S/cm. This is suitable for use as a conductive film. By incorporating a sulfonate counterion, the conductivity of the composite is significantly improved. Further, by incorporating a heat activated cross-linking agent such as a peroxide, the tensile strength of the processed polymer is significantly improved.

  • Patent number: 5219930
    Abstract: Processes for converting vinyl alcohol polymers to poly(keto-esters) and the novel products obtained therefrom are disclosed. The process involves reacting a vinyl alcohol polymer, such as PVA or EVOH, with an organic peroxyacid oxidizing agent in an inert liquid medium at a temperature from -20.degree. C. to 150.degree. C. to convert the secondary hydroxyl groups of the vinyl alcohol polymer to carbonyl and oxycarbonyl groups. In another aspect of the invention, the vinyl alcohol copolymer is first reacted with an oxidizing agent capable of converting the secondary hydroxyl groups to carbonyl but not to oxycarbonyl and then subsequently oxidized using a peroxyacid to form oxycarbonyl. The poly(keto-esters) comprised of carbonyl units, oxycarbonyl units, hydroxyl-containing units and units which are primarily hydrocarbons in nature are photodegradable and biodegradable.

  • Patent number: 5064912
    Abstract: A process for converting the pendant keto groups of ketonic polymers to ester groups is provided. The process involves reacting the polymer with an organic peroxyacid oxodizing agent in an inert liquid medium at a temperature from -20.degree. C. to 150.degree. C. to convert substantially all or only a portion of the pendant carbonyl functionality to oxycarbonyl moieties. Homopolymers or copolymers of .alpha., .beta.-unsaturated ketones, such as methyl vinyl ketone and ethyl vinyl ketone, are readily modified with the process of this invention.

  • Patent number: 5064932
    Abstract: Novel poly(keto-esters) having carbonyl and oxycarbonyl units randomly combined with linking units derived from olefinic monomers to form an essentially straight-chain polymer backbone are provided. The poly(keto-esters) are produced by converting a portion of the carbonyl functionality of a polyketone to oxycarbonyl groups. The conversion is achieved by reacting the polyketone with an organic peroxyacid in an inert liquid medium at a temperature from -20.degree. C. to 150.degree. C.

  • Patent number: 5004568
    Abstract: A method is disclosed for the production of esters by reaction of an allylic ether with carbon monoxide in the presence of a catalytically effective amount of a Group VIII noble metal catalyst and a Group IB metal halide to obtain esters. The Group IB metal halide is present in an amount sufficient to prevent the catalyst from being converted into a Group VIII metal during the reaction. When the reaction is conducted in the presence of a quaternary ammonium salt the ester may be extracted by solvent extraction to minimize catalyst decomposition caused when extractive distillation is used to separate the ester.

  • Patent number: 4957997
    Abstract: A facile process for converting polyketones containing pendant functional groups to polyesters is provided. The process involves reacting the polyketone with an organic peroxyacid oxidizing agent in an inert liquid medium at a temperature from -20.degree. C. to 150.degree. C. to convert substantially all or only a portion of the keto functionality to ester moieties. The polyketones are obtained by copolymerizing carbon monoxide and a vinyl or vinylidene monomer having at least one functional group containing one or more oxygen, nitrogen, sulfur or halogen atoms.
