    摘要： A method of making a polyether polymer comprises reacting a salt of a dihydroxy-substituted aromatic hydrocarbon with a substituted aromatic compound of formula (I) Z(A1—X1)2   (I) in the presence of a catalyst to form an intermediate polymer having endgroups, wherein the molar ratio of the salt of a dihydroxy-substituted aromatic hydrocarbon to the substituted aromatic compound is less than 1, Z is an activating radical, A1 is an aromatic radical and X1 is fluoro, chloro, bromo or nitro; determining the additional amount of the salt of a dihydroxy-substituted aromatic hydrocarbon needed to form a final polyether polymer with a predetermined molecular weight and adding the additional amount of the salt of a dihydroxy-substituted aromatic hydrocarbon to the intermediate polymer.

    摘要： Polyether polymers, such as polyetherimides, are prepared by the reaction of a dihydroxy-substituted aromatic hydrocarbon alkali metal salt, such as bisphenol A disodium salt, with a bis(N-(chlorophthalimido))aromatic compound, such as 1,3- and/or 1,4-bis(N-(4-chlorophthalimido))benzene, in a solvent such as o-dichlorobenzene and in the presence of a phase transfer catalyst such as a hexaalkylguanidinium chloride. Several embodiments may be employed to improve the method. They comprise employing substantially dry reagents, employing a high solids level in solvent, beginning with an excess of bis(N-(chlorophthalimido))-aromatic compound and incrementally adding alkali metal salt, employing alkali metal salt of small particle size, and using reagents of high purity.

    摘要： Bis(halophthalimides) are prepared in mixture in an organic liquid such as ortho-dichlorobenzene or anisole, by a reaction at a temperature of at least 150° C. between at least one diamine compound and at least one halophthalic anhydride in the presence of imidization catalyst. The reaction mixture is maintained at about 15% by weight solids content and rich in the halophthalic anhydride by constantly monitoring the reaction mixture using analytical methods such as high performance liquid chromatography. The product mixture may be directly employed in the direct preparation of polyetherimides, and similar slurries may be employed to prepare other polyether polymers.

    摘要： The present invention provides a process for recovering a metal nitrite, e.g., sodium nitrite, from a reaction mixture formed from an aromatic displacement reaction such as the synthesis of an aromatic bis(ether phthalimide) in an organic non-polar solvent. The process comprises forming a reaction mixture from the synthesis of an aromatic bis(ether phthalimide) comprising a recoverable amount of metal nitrite; treating the reaction mixture with an amount of water effective to produce an aqueous solution phase of metal nitrite and an organic non-polar phase; and separating the aqueous solution phase of metal nitrite from the organic non-polar phase.
