Structure of amorphous films containing tri-p-tolylamine and bisphenol-A polycarbonate as determined by high-resolution carbon-13 NMR of partially deuterated samples in the solid state. Hewitt, J. Michael; Henrichs, Paul M.; Scozzafava, M.; Scaringe, R. P.; Linder, M.; Sorriero, L. J. (Res. Lab., Eastman Kodak Co., Rochester, NY 14650, USA). Macromolecules, 17(12), 2566-72 (English) 1984. CODEN: MAMOBX. ISSN: 0024-9297. DOCUMENT TYPE: Journal CA Section: 36 (Physical Properties of Synthetic High Polymers) High-resoln. solid-state NMR is used to probe the short-range ordering and specific interactions of ri-p-tolylamine [1159-53-1] with bisphenol A polycarbonate [24936-68-3] in amorphous films. The technique involves intermol. cross polarization from species contg. protons to completely deuterated species. Resonances from carbons in completely deuterated mols. are visible in the cross-polarized spectrum only as a result of cross polarization from protons in neighboring mols. The transfer of magnetization, which is dependent on the dipolar coupling between the protons and the carbon, is explored as a probe of site-specific interactions and spatial arrangements in the film.

CLASS: IC: G03G005-06; G03G005-04; G03G005-07. APPLICATION: JP 81-73031 14 May 1981. DOCUMENT TYPE: Patent CA Section: 74 (Radiation Chemistry, Photochemistry, and Photographic and Other Reprographic Processes) Electrophotog. photosensitive materials contain charge-generating bisazo pigment of the formula RN:NZN:NR1 (R = I, II, III, IV, V, VI, VII; R1 = aryl, heterocyclic moiety; R2 = OH, NR8R9, NHSO2R10; R3 = halo, alkyl, alkoxy, CO2H, SO3H, carbamoyl, sulfamoyl; R4 = H, amino, alkyl, carbamoyl, carboxy or its ester; R5 = aryl; R6, R7 = alkyl, aralkyl, aryl; R8, R9 = H, alkyl; R10 = alkyl, aryl; Z = divalent arom. or heterocyclic moiety; A = arom. or heterocyclic ring, n = 1,2; m = 0, 1, 2). 88878-36-8 and 1159-53-1 which are cas registry numbers of chemicals are mentioned. Thus, an Al-laminated polyester film support was coated with a soln. of 1-[4-(4-hydroxyphenylazo)phenylazo]-2-hydroxy-N-phenyl-3-naphthamid e, and coated with a compn. contg. 1-phenyl-3-(p-diethylaminostyryl)-5-(p-diethylaminophenyl)pyrazoline and Panlite L-1250 (a polycarbonate resin) to give a composite electrophotog. plate having good sensitivity. .
