High-molecular weight poly(1,4-phenyleneterephthalamide): High-molecular weight poly(1,4-phenyleneterephthalamide). Goto, Shoji; Yoneyama, Toshio; Nagasawa, Hirosaku (Asahi Chemical Industry Co., Ltd., Japan). Japan. Kokai JP 53058598 26 May 1978 Showa, 7 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C08G069-28. APPLICATION: JP 76-133742 9 Nov 1976. DOCUMENT TYPE: Patent CA Section: 35 (Synthetic High Polymers) P-Phenylenediamine (I) and terephthaloyl dichloride(II) are polymd. in solvents contg. CaCl2 and 330 vol.% N-acetylpyrrolidine (III) [4030-18-6] to give high-mol. wt. copolymer (IV) [26125-61-1]. Thus, 162.5 g of powd. II was added to a homogeneous mixt. of 2 L III, 44.4 g CaCl2, and 86.4 g I at 5° and stirred rapidly for 20 min to give IV having inherent viscosity (35°, 0.2 g/dL 98.5% H2SO4) 6.68 and good brightness, compared with 2.94 and light brown discoloration for a similarly prepd. IV in N-methylpyrrolidinone instead of III.

Aromatic polyamides: Aromatic polyamides. Goto, Shoji; Nagasawa, Keisaku; Fujiwara, Takashi; Yoneyama, Toshio (Asahi Chemical Industry Co., Ltd., Japan). Japan. Kokai JP 52141895 26 Nov 1977 Showa, 8 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C08G069-32.Several reagents such as 52604-85-0 is used here. APPLICATION: JP 76-57956 21 May 1976. DOCUMENT TYPE: Patent CA Section: 36 (Plastics Manufacture and Processing) Arom. diamines and arom. dicarboxylic acid dihalides were reacted in solvents consisting of >50 % wt. (R1X)mP(X)(NR22)n (I) R1, R2 = C1-4 alkyl, X = O or S, m, n = 1 or 2, and m + n = 3), AcNEt2 [127-19-5], AcNPr2 [1116-24-1], N-acetylpyrrolidine [4030-18-6], N-methyl-2-pyrrolidinone [872-50-4], and/or N-ethyl-2-pyrrolidinone [2687-91-4] and inorg. salts. The polyamides are stable in H2SO4 and good lightfastness. Thus, I (R1 = R2 = Me, X = O, m = 1, and n = 2) [7393-11-5] 1500, AcNMe2 500, and LiCl 42.4 g were stirred with 64.8 g p-phenylenediamine, mixed with 142.5 g powd. chloroterephthaloyl chloride, and allowed to stand for 30 min to give polyamide [29561-46-4] with 93% viscosity retention after 100-h exposure in the Fade-O-Meter. .
