    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: 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.

    摘要: Poly(arylene sulfide/sulfone) polymers are treated in order to increase melt stability and decrease impurities by contacting the poly(arylene sulfide/sulfone) polymer with a soluble zinc compound and an acidic solution. In one embodiment, the polymer is treated first with the soluble zinc compound, followed by treatment with the acidic solution. In another embodiment, the polymer is treated in one step with a solution comprising a water soluble zinc compound in an acidic solution.
