  • Patent number: 7834106
    Abstract: Regioregular poly(3-alkylthiophenes) and other polythiophenes can be prepared by living polymerization which have good solubility, processability and environmental stability. The polymerization method can afford regioregular poly(3-alkylthiophenes) in high yields. Kinetic study of polymerization revealed the living character of this process. The molecular weight of poly(3-alkylthiophenes) is a function of the molar ratio of the monomer to nickel initiator, and conducting polymers with relatively narrow molecular weight distribution (PDI<1.5) are now readily available. Sequential monomer addition resulted in new block copolymers containing different poly(3-alkylthiophene) segments, which further confirms the “livingness” of this system. Other synthetic methods can be used as well to conduct living polymerization. Blends and electronic devices can be prepared.

    Abstract: A method for producing polyphenylene sulfide (PPS) polymer, including polymerizing reactants in a reaction mixture in a vessel to form PPS polymer in the vessel, measuring values of operating variables of the vessel and/or PPS process, and determining the amount of quench fluid to add to the vessel based on the values of the operating variables. The technique may rely on the vapor liquid equilibrium (VLE) of the mixture to calculate the concentration of water existing in the reactor prior to quench, and accounts for the effectiveness of the upstream dehydration process and in the amount of water produced during the polymerization. The technique is a striking improvement over the trial-and-error estimation of the amount of quench water based on human operating experience, and avoids direct measurements of the existing water concentration in the reactor. The result is improved control of PPS particle size and other properties.

  • Patent number: 5621069
    Abstract: A technique is described for the preparation of conjugated arylene and heteroarylene vinylene polymers by thermal conversion of a polymer precursor prepared by reacting an aromatic ring structure with an aqueous solution of an alkyl xanthic acid potassium salt. In this processing sequence the xanthate group acts as a leaving group and permits the formation of a prepolymer which is soluble in common organic solvents. Conversion of the prepolymer is effected at a temperature ranging from 150.degree.-250.degree. C. in the presence of forming gas. Studies have shown that electroluminescent devices prepared in accordance with the described technique evidence internal quantum efficiencies superior to those of the prior art due to the presence of pinhole free films and therefore permit the fabrication of larger area LED's than those prepared by conventional techniques.

  • Patent number: 5597887
    Abstract: Blow moldable polycarbonate is produced by first producing a polycarbonate preform by a melt transesterification process. The polycarbonate preform comprises 2.1 to 10 mole percent polyfunctional branching agent, based on the total moles of polycarbonate in the polycarbonate preform. The polycarbonate preform is then melt equilibrated with a second polycarbonate to produce a blow moldable grade.

  • Patent number: 5162470
    Abstract: Novel conjugated stilbenylene polymers are disclosed having non-linear optical properties, and which can be converted to electrically conductive polymers. Such polymers are produced by reacting a novel bis-cycloalkylene sulfonium salt of 2,5-dimethyl stilbene, e.g. 2,5-(4' -methoxy)-stilbene dimethylene bis-(tetramethylene sulfonium bromide), with alkali metal hydroxide to form a cycloalkylene sulfonium salt precursor polymer, and then heating the precursor polymer under conditions to produce the stilbenylene vinylene polymer, e.g. poly(2,5-(4'-methoxy)stilbenylene vinylene).

  • Patent number: 5097008
    Abstract: Branched polycarbonates are prepared by melt equilibration of aromatic cyclic polycarbonate oligomers with a polyhydric phenol having more than two hydroxy groups per molecule, preferably 1,1,1-tris-(4-hydroxyphenyl)ethane, in the presence of a carbonate equilibration catalyst, preferably tetrabutylammonium tetraphenylborate. In an additional embodimetn of the invention, a linear aromatic polycarbonate is added to the reaction mixture. Branched polycarbonates prepared according to this inventin have high melt strength and high shear sensitivity characteristics and are useful in extrusion and injection molding processing applications and particularly useful in blow molding applications for preparing relatively large articles and panels.

  • Patent number: RE40813
    Abstract: The present invention relates to polythiophenes, particularly regioregular head-to-tail poly(3-alkylthiophenes) (HT-PATs), block copolymers made therefrom, and their methods of formation. The present invention provides HT-PATs with well-defined, specific end-groups, functionalization of the defined HT-PATs, and incorporation of end group functionalized HT-PATs into block copolymers with structural polymers. The intrinsically conductive diblock and triblock copolymers, formed from the HT-PATs, have excellent conductivity and low polydispersities that are useful in a number of applications. The block copolymers of the present invention have been found to exhibit conductivities that range from a low of 10?8 S/cm for certain applications to as high as several hundred S/cm or more.
