| titleOfInvention | SOLUBLE SOLOPOLINAPHTOYLENEIMIDES AS A THERMAL-RESISTANT MATERIAL AND METHOD FOR OBTAINING SOLUBLE SOPOLIN-PHTOYLENEMIDES |
| abstract | The invention relates to the chemistry of high-molecular compounds, namely, to new copolynafluoroylene imides, characterized by high heat resistance, solubility in a large number of solvents, resistance to aggressive media. They can be used to produce films, fibers, binders for fiberglass. The invention allows to increase the heat resistance of copolinaphtoylenimides by synthesizing polymers of the formula where R is —O—; -CH-; -NH-; n = 70 - 200; m = 130 - 20, mol. 80 - 120 thousand, which is carried out by the interaction of 1,4,5, 8-naphthalene tetracarboxylic acid and a mixture of diamines-4,4′-diaminodiphenylamine-2-sulfonic acid and 4,4 ′-diaminodiphenyloxide, or 4,4′-diaminodiphenylmethane , or 4,4′-diaminodiphenylamine, taken in a ratio of from 90 to 10 to 50 to 50 wt.%, and the process is carried out in an environment of N-methylpyrrolidone, containing 10 wt.% water, 18 to 54 wt. % of acetic acid and 0.2 - 1.8 wt.% alkali metal hydroxide, at 70 - 80C for 3 - 5 hours. 2 s. the item f., 4 tab. |
