摘要： 1469936 Aromatic bis(ether anhydrides) GENERAL ELECTRIC CO 22 March 1974 [30 March 1973] 12865/74 Heading C2C Aromatic bis(ether anhydrides) are prepared by reacting an alkali metal diphenoxide of formula and an aromatic anhydride of formula where X and Y are each nitro or a halogen atom, M is an alkali metal ion, and R is a divalent aromatic radical of 6-30 carbon atoms, preferably either (a) one of the divalent aromatic radicals or (b) a radical of the formula where Q is a divalent radical of the formula -O- or -S- where m is 0 or 1, and y is a whole number from 1 to 5. The aromatic bis- (ether anhydrides) of formula where R 1 is and Q 1 is -O-, -S-, -C(CH 3 ) 2 - or -SO 2 - are novel. The compounds of the invention are used as intermediates in the preparation ofpolyimides and polyesters, and as curing agents for epoxy resins.

摘要： There are provided bis(thioether) aromatic dianhydrides and method for making these materials. A bisthiol in the presence of base, or bisthiol basic salt, can be reacted with a nitro- or halo-substituted phthalic compound, such as an anhydride or anhydride precursor. These aromatic dithiodianhydrides can be used to make polyimides and polyesters, and can be used as curing agents for epoxy resins.

摘要： Aromatic ether anhydrides of formulae (I) and (II) can be obtd. by reaching an alkali metal phenoxide, R-X-M and with a nitro- or halo-substd. aromatic anhydride of formulae (III) or (IV): (where M is Na+, K+, Li+, Rb+, R is phenyl tolyl, xylyl, naphthyl, anthryl and their halogenated derivs, X is -O- or -S- and Y is NO2, Cl, F, Br, or I); and recovering (I) or (II) from the mixt. (I) and (II) can be used as curing agents for epoxy resins, polyester resins, polyimide chain terminators and hydrocarbon grease antioxidants.

摘要： A method is provided for making alkali metal bisphenoxide salts by refluxing a heterogenous mixture of a non-polar organic solvent and an aqueous solution of an alkali metal bisphenoxide. These bisphenoxide salts can be used thereafter to make aromatic bis(ether phthalimides) by reaction with nuclear ring substituted N-organo phthalimides.

摘要： Aromatic bisimides can be prepared by effecting reaction between a 3- or 4-nitro-N-substituted phthalimide with an aromatic dihydroxy compound in the presence of a solid alkali-metal hydroxide and using a certain class of dipolar aprotic compounds, e.g., dimethyl formamide, as a solvent.

摘要： 1482664 Polyetherimides GENERAL ELECTRIC CO 29 July 1974 [28 Sept 1973] 33388/74 Heading C3R A method of making polyetherimides consisting essentially of combined units comprises reacting substantially equimolar amounts of an alkali metal salt of a dihydric phenol MOROM and a bis-imide in the presence of a "dipolar aprotic organic solvent" (defined as having a dielectric constant greater than 20) at up to 100 C. and thereafter recovering the polyetherimide. In the formulµ M is an alkali metal ion; R is a C 6-30 divalent organic radical; and R 1 is alkylene, C 3-20 cycloalkylene, a C 6-20 aromatic hydrocarbon radical or an alkyl, alkoxy or halo-derivative thereof, a C 1-5 alkylene-terminated polydiorganosiloxane, or where Q is -O-, -CO-, -SO 2 -, -S- or -C x H 2x -; x is 1 to 5 and m is 0 or 1. It is stated that the use of the bis-(fluorophthalimide) enables the polyetherimides to be obtained in considerably less time and to attain significantly higher intrinsic viscosities than when using a bis-(chlorophthalimide). Reference has been directed by the Comptroller to Specification 1,392,649.
