摘要： Disclosed herein are methods for manufacturing a functionally graded polymer material. A method comprises preparing a melted polymer mixture comprising a thermoplastic polymer and a magnetic filler; molding the melted polymer mixture; and applying a magnetic field to a portion of the melted polymer mixture to form the functionally graded article, wherein as the melted polymer mixture flows into the mold, the melted polymer mixture comes into contact with the magnet field. Another method comprises molding the melted polymer mixture; and applying a magnetic field from a first magnet to a first portion of the melted polymer mixture and applying a magnetic field from a second magnet to a second portion of the melted polymer mixture to form the functionally graded article, wherein the first magnet and the second magnet are positioned in a manner such that the magnetic field produced by each are nonoverlapping.

摘要： A process for the purification of an oxydiphthalic anhydride includes contacting a mixture of an oxydiphthalic anhydride and at least one of the corresponding oxydiphthalic diacid, a corresponding oxydiphthalic tetraacid, a halophthalic anhydride, and a catalyst with a solvent to provide a slurry. The solvent is capable of solubilizing the corresponding oxydiphthalic diacid, the corresponding oxydiphthalic tetraacid, the halophthalic anhydride, and the catalyst at a temperature of 15 to 50° C., and the oxydiphthalic anhydride is substantially insoluble in the solvent at this temperature. The oxydiphthalic anhydride can be isolated from the slurry. A purified oxydiphthalic anhydride and a polyetherimide prepared therefrom are also disclosed.
