Poly oxadiazole

Oxalon Grodno KHIMVOLO- KNO Poly(oxadiazole) fiber... [Pg.250]

Oxamidrazone, NHj—NH—C(NH)—C(NH)—NH—NH2, is produced from dicyan and hydrazine, and its isomer converted with terephthaloyl chloride to poly(terephthaloyl oxamidrazone), PTO. PTO can be converted to a poly(triazole), a poly(oxadiazole), or to a metal ion chelated polymer ... [Pg.500]

Poly(triazoles) and poly(oxadiazoles), each with two hetero rings per repeat unit, are obtained by the process described in the previous section. Poly(triazoles) with one triazole residue per structural element are produced from terephthalic acid and hydrazine with subsequent cyclocondensation of... [Pg.501]

The poly(triazole) produced has a very high glass transition temperature of 260 C. It can be wet or dry spun from formic acid. The fibers still retain 30% of their original elongation at break even at 300 C. But to obtain poly(oxadia-zole) fibers, poly(phenylene hydrazide) is spun. Water is eliminated from their drawn or undrawn fibers to produce poly(oxadiazole) fibers. [Pg.502]

Much work has been done on this interesting group of condensation polyimides [219]. Trying to combine the good thermal stability of other heterorings and the availability of polyimide monomers, a considerable number of mixed polyheterocycles has been synthesized. Among other heterocyelic copolyimides, poly(imidazole imide)s [220,221], poly(oxadiazole imide)s [222,223], poly(benzazole imide)s [224,225], poly(quinoxaline-imide)s [226], and poly(quinazolinedione imide)s [227] have been synthesized. [Pg.585]
