B, 19(6), 457-60 (Russian) 1977. CODEN: VYSBAI. DOCUMENT TYPE: Journal CA Section: 35 (Synthetic High Polymers) The title polyquinoxaline (I) [52276-31-0] was prepd. by polycondensation of 1,4-bis(phenylglyoxaloyl)benzene (II) [3363-97-1] and 3,3',4,4'-tetraminodiphenyl ether (III) [2676-59-7]. The reported data included heat capacities of I, II, and III, glass transition temp. of I, heat of combustion and formation of I, II, and III, heat of fusion and polymn. of II and III, enthalpy, entropy, and free energy of I, II, and III, entropy of fusion of II and III, entropy and free energy of formation of I, II, and III, and entropy and free energy of polymn. of II and III to I.

Thermal polycyclocondensation of polyheteroarylenes at temperatures lower than the melting temperature of the starting monomers: Thermal polycyclocondensation of polyheteroarylenes at temperatures lower than the melting temperature of the starting monomers.

CODEN: DANKAS. ISSN: 0002-3264. DOCUMENT TYPE: Journal CA Section: 35 (Chemistry of Synthetic High Polymers) Thermal polycondensation of 3,3',4,4'-tetraaminodiphenyl ether [2676-59-7] with phthalic anhydride [85-44-9], 1,4-bis(phenylglyoxyloyl)benzene [3363-97-1], 1,4,5,8-naphthalenetetracarboxylic dianhydride [81-30-1], 3,3',4,4'-benzophenone tetracarboxylic dianhydride (I) [2421-28-5], and p,p'-diaminodiphenyl ether [101-80-4] with I took place in the absence of solvents at temps. lower than the melting temp. of the lowest-melting component of the monomer mixt. The occurrence of the polycondensation was attributed not only to lowering the melting temp. of the lowest-melting component by the presence of the comonomer, but also to the interaction of the vapors of easily sublimable component with the solid comonomer, i.e., to the heterogeneous gas-solid reaction.
