Study on hydrolysis of polyimide and polyphenylquinoxaline

Study on hydrolysis of polyimide and polyphenylquinoxaline. Lu, Fengcai; Liang, Desheng; Lai, Zhugen; Bai, Luna; Gao, Yuanming (Inst. Chem., Acad. Sin., Beijing, Peop. Rep. China). Sci. Sin., Ser. B (Engl. Ed.), 29(4), 345-52 (English) 1986. CODEN: SSBSEF. ISSN: 0253-5823. DOCUMENT TYPE: Journal CA Section: 35 (Chemistry of Synthetic High Polymers) Section cross-reference(s): 36, 73 The electron densities of 2 model compds., N-phenylphthalimide [520-03-6] and 2,3-diphenylquinoxaline [1684-14-6], were calcd. by means of the CNDO/2 method, and hydrolysis of the model compds. and polymers was carried out. The theor. calcn. and expts. both proved that poly(diphenylbisquinoxalinephenylene) had good hydrolytic stability while poly(oxydianilinepyromellitimide) [25036-53-7] completely hydrolyzed under the same exptl. condition. The mechanism of hydrolysis was also predicted.
