    摘要: Branched aromatic sulfide sulfone polymer is produced by contacting at least one dihalo aromatic sulfone, at least one polymerizable sulfur source other than lithium sulfide, at least one alkali metal carbonate, at least one organic amide, at least one alkali metal carboxylate, at least one polyhalodiarylsulfone having more than two halogen substituents and water including water of hydration under polymerization conditions for a period of time sufficient to form an aromatic sulfide sulfone polymer. The polymer exhibits higher melt and solution viscosity than obtained in the same process except without the use in the reaction mixture of polyhalodiarylsulfone having more than two halogen substituents and is useful in the production of coatings, films, molded objects, and fibers.

    摘要: This invention provides a process to produce aromatic sulfide/sulfone polymers exhibiting high molecular weight, and having a light or "whitish" coloration. This process employs a dihaloaromatic sulfone, a sulfur-containing compound and a 1,3-dialkyl-2-imidazolidinone. These lighter colored polymers are more preferable commercially and may be useful in the production of coatings, films, molded objects, and glass or carbon fiber composites.

    摘要: A two-step process to make a poly(arylene sulfide sulfone) polymer containing ether groups having high molecular weights is described. In the first step an aromatic diphenol, a dihaloaromatic sulfone, a polar organic compound and an alkali metal base are reacted at an elevated temperature for a time period in the range of 1 minute to 2 hours. A sulfur source is then added to form a poly(arylene sulfide sulfone) polymer containing ether groups. An alkali metal carboxylate is also present in the second step. The polymers prepared by the invention method exhibit higher inherent viscosities, indicating higher molecular weight.

    摘要: An aromatic sulfide/ketone polymer is prepared from a dihaloaromatic ketone, alkali metal sulfide, water and a polar organic compound. The polymerization reaction mixture is subjected to a heat soak at an elevated temperature, then a separation agent is added under controlled conditions and the mixture is subsequently cooled to provide a mixture comprising particulate aromatic sulfide/ketone polymer. Biaxially-oriented film is made from the recovered particles of aromatic sulfide/ketone polymer by (1) washing the polymer particles with an aqueous calcium salt, (2) heating the washed particles to remove water, (3) molding the heated particles to form a sheet of polymer, (4) biaxially stretching the sheet above the glass transition temperature of the polymer to form a film, and (5) heat-setting the biaxially-oriented film under stretching tension for a time and at a temperature to increase strength properties and density.

    摘要: Poly(arylene sulfide) polymers containing sulfone, ether and biphenyl groups are prepared by a two step process. In the first step, a diphenol is reacted with either a dihaloaromatic sulfone monomer or a bis(haloarylsulfonyl) biphenyl monomer, or both, in the presence of an alkali metal base and a polar organic compound. In the second step, the reaction mixture above is reacted with a sulfur source, and any monomer which was not employed in the first step, if any. The polymers prepared according to the invention process exhibit increased glass transition temperatures over those of known poly(arylene sulfide) polymers. The structure of repeating units of the polymer can be controlled by varying the sequence of addition of the monomers.
