摘要： Aromatic bis(ether anhydride)s can be made by a nitro displacement of an N-substituted nitrophthalimide with an alkali (diphenoxide to produce an intermediate aromatic bis(etherphthalimide). Hydrolysis of the aromatic bis(etherphthalimide) to the corresponding tetra-acid salt followed by acidification and dehydration, results in the production of the aromatic bis(ether anhydride). These anhydrides can be used as intermediates for making polyimides. The intermediate aromatic bis(etherphthalimide) can be employed as a plasticizer in polyimide resins.

摘要： 1374767 Laminates IMPERIAL CHEMICAL INDUSTRIES Ltd 17 Jan 1972 [29 Jan 1971] 3473/71 Heading B5N [Also in Division C3] A fabric is coated with a copolyamide and contacted with a second fabric surface, and heat is applied to soften the copolyamide, thus bonding the fabrics. The copolyamide contains, randomly distributed, by weight: 10-80% -[-CO (CH 2 ) 5 NH-]-; 10-80% -[-NH(CH 2 ) 6 - NHCO(CH 2 ) x CO-]- or -[-NH(CH 2 ) 6 NH-COAr-CO-]-, where x is 2, 3, 5, 6, 7, 9 or 10, and Ar is a monocyclic aromatic nucleus; 1-70% -[-CO(CH 2 ) 11 NH-]-, and 0-10% other amide monomer units. The "other units" may be derived from salts of hexamethylene diamine with adipic or sebacic acids, or salts of ethylenediamine or tri-, tetra-, penta-, deca-, or dodecamethylenediamine with HOOC(CH 2 ) x COOH or with a monocyclic aromatic dicarboxylic acid. The polymer may contain: glass fibres, mica, carbon, or chalk, pigments, or plasticizers or flow improvers, e.g. stearates or silicates of Mg, Al, Ca, or Zn, or tallow amines, and may be made into films, fibres, filaments or shaped articles. Or the copolyamide may be a powder having number-average particle-size

摘要： 1359024 Polysiloxane foam stabilizers IMPERIAL CHEMICAL INDUSTRIES Ltd 9 Nov 1972 [22 Nov 1971] 54120/71 Headings C3T and C3C A foam stabilizer suitable for use in the production of foams from plastisols comprises at least one copolymer consisting of (A) R 3 SiO 0À5 , (B) RSiO 1À5 and (C) SiO 2 units wherein R is an alkyl, monocyclic aryl hydrocarbon, alkaryl or aralkyl radical the ratio of A to B + C units being 0À6 : 1 to 1À5 : 1 and of B : C units 0À05 : 1 to 1 : 1. The copolymers can be prepared by cohydrolysing a mixture of R 3 SiX, RSiX 3 and SiX 4 where X is a halogen, or by the addition of a blend of R 3 SiX and RSiX 3 in a solvent to a stabilized silica hydrosol, or by the addition of a solution of R 3 SiX to a stabilized hydrosol of silica and methylsiliconic acid. In the production of a solid thermoplastic foam, a plastisol or a thermoplastic resin, preferably a vinyl chloride polymer, having at least one of the above polysiloxane copolymers dispersed therein is foamed with a gas or vapour introduced mechanically, and the foam so produced is heated to cause gelation and fusion thereof and then cooled. Preferred resins are vinyl chloride/ vinyl acetate copolymers containing up to 20% wt. polymerized vinyl acetate. In the examples various polysiloxane copolymers in which R is methyl are prepared by the above methods and are used as stabilizers in the preparation of foams from plastisols comprising (1) vinyl chloride polymer and as plasticizer dialkyl phthalate, butyl benzyl phthalate and mixtures thereof, and (2) vinyl chloride/vinyl acetate copolymer and as plasticizer a mixture of dialkyl phthalate, butylbenzyl phthalate and chlorinated paraffin in varying proportions, and the foam densities are determined.
