Polyimides prepared from perfluoroisopropylidene diamine: Jones, Robert J.; O'Rell, Michael K.; Hom, Jim M. (TRW Inc., USA). U.S. US 4111906 5 Sep 1978, 4 pp. (English). (United States of America). CODEN: USXXAM. CLASS: IC: C08G073-10. NCL: 528229000. APPLICATION: US 76-706880 19 Jul 1976. DOCUMENT TYPE: Patent CA Section: 35 (Synthetic High Polymers) Section cross-reference(s): 25 An arom. F-contg. diamine was prepd. and used in the manuf. of heat-resistant polyimides. Thus, 2,2-bis(4-hydroxyphenyl)hexafluoropropane [1478-61-1] was condensed with 4-chloronitrobenzene [100-00-5] to give 93% 2,2-bis[4-(4-nitrophenoxy)phenyl]hexafluoropropane [69563-87-7] which was reduced to the resp. diamine (I) [69563-88-8]. An equimolar amt. of benzophenonetetracarboxylic acid dianhydride in AcNMe2 was added dropwise to the I soln. under N with cooling. The intermediate polyamic acid was imidized by heating 4 h to 180° to give a tough flexible polyimide [69572-62-9] of inherent viscosity 0.47 dL/g (H2SO4, 30°); initial wt. loss occurred at 420° (in air).
