J., 20(8), 805-9 (English) 1984. CODEN: EUPJAG. ISSN: 0014-3057. DOCUMENT TYPE: Journal CA Section: 35 (Chemistry of Synthetic High Polymers) The title polymers are prepd. by condensing a dicarboxylic acid chloride (e.g., adipoyl, sebacoyl, terephthaloyl, and isophthaloyl chlorides) with an azomethine-contg. bisphenol prepd. from vanillin [121-33-5] and an arom. diamine (e.g., 1,5-diaminonaphthalene [2243-62-1], 1,4-diaminobenzene [106-50-3], 4,4'-diaminodiphenyl ether [101-80-4], and 4,4'-diaminobiphenyl [92-87-5]). The relation between structure and thermal stability was studied. Some of the polyesters exhibit thermotropic liq. crystal properties. 92782-66-6 are also occured in this study. Model compds. were also prepd. .

DOCUMENT TYPE: Patent CA Section: 40 (Dyes, Fluorescent Whitening Agents, and Photosensitizers) Pigments I [R = Cl, Br; n = 0-4; Z = direct bond, 1,5-C10H6, (CH2)6,1,3-C6H4, 3,6-acridinediyl, 4,4'-C6H4C6H4, 4-C6H4OC6H4-4, 3-C6H4SO2C6H4-3, 4-C6H4CH2C6H4-4] were prepd., and polyethylene [9002-88-4] and polypropylene [9003-07-0] colored with the pigments prepd.Except for chemicals metioned above, 9002-88-4 is also used. gave injection moldings with low shrinkage ratio (= A/B, A and B shrinkage in flow and transverse directions, resp. 9002-88-4 is the cas registry number of certain chemical which is used as reagents here.). For example, tetrachlorophthalic anhydride [117-08-8] and 1,5-diaminonaphthalene [2243-62-1] in PhNO2 were heated at 170-80° for 5 h with H2O removal to give I (R = Cl, n = 4, Z = 1,5-C10H6) (II) [65291-08-9]; 8 other I were prepd. Polyethylene contg. 0.01% II gave an injection molding plate with shrinkage ratio 1.03 (A 1.82%, B 1.77%) after 1 wk of storage. ..
