    摘要： A long-acting super-hydrophobic anticoagulant biological valve and a preparation method therefor. The preparation method includes the following steps: (1) treating a biological valve material with glutaraldehyde; (2) placing the biological valve material treated in step (1) into an acid liquid containing a polyphenol compound and metal ions, and adding an oxidant for reaction; and (3) reacting the biological valve material treated in step (2) with a hydrophobic substance. According to the method, a super-hydrophobic coating having a long-acting high water contact angle and a low rolling angle is prepared on the surface of the biological valve by means of a simple and stable operation process without affecting the performance of the valve body, and the requirements of long-acting anticoagulation are met by resisting the adsorption of plasma proteins.

    摘要： A method of making a poly(phenylene ether) includes oxidatively polymerizing a combination of a phenolic monomer and a monofunctional phenylene ether oligomer in the presence of an organic solvent and a copper-amine catalyst. The method further includes terminating the oxidative polymerization to form a post-termination reaction mixture; combining an aqueous solution comprising a chelant with the post-termination reaction mixture to form a chelation mixture including an aqueous phase having chelated copper ion, and an organic phase having dissolved poly(phenylene ether); separating the aqueous phase and the organic phase; and isolating the poly(phenylene ether) from the organic phase.

    摘要： A method of preparing a poly(arylene ether) includes oxidatively coupling a monohydric phenol in a reaction solution at a reaction temperature that exceeds the cloud point temperature of the reaction solution. The oxidative coupling occurs in the presence of a metal complex catalyst, and when the catalyst includes an amine ligand, the method facilitates incorporation of the amine ligand into the poly(arylene ether) resin. The amine-incorporated poly(arylene ether) resins prepared by the method are useful in the preparation of higher molecular weight poly(arylene ether) resins and compatibilized blends of poly(arylene ether) resins with other thermoplastics.

    摘要： A polyfunctional poly(arylene ether) resin may be prepared by a method that includes oxidatively copolymerizing a monohydric phenol and a polyhydric phenol in an aromatic hydrocarbon solvent in the presence of a catalyst comprising a metal ion and a nitrogen-containing ligand to form a solution comprising a polyfunctional poly(arylene ether) having an intrinsic viscosity of about 0.04 to about 0.3 deciliter per gram at 25°C in chloroform; and contacting the polyfunctional poly(arylene ether) solution with an aqueous solution of a chelating agent to extract the metal ion from the solution; wherein the chelating agent and metal ion are present in a molar ratio of about 1.0 to about 1.5. The method reduces the formation of a dispersion during the chelation step.
