Abstract

PURPOSE: To obtain titled cpd. which has good heat resistance and produces a resinous substance having excellent solubility in org. solvents, by a method wherein an arom. diaminosulfonamide is reacted with a dibasic acid halide to obtain polyamidosulfonamide which is then subjected to a dehydration-cyclization reaction.
CONSTITUTION: An arom. diaminosulfonamide of formula I (wherein Ar is trivalent arom. gp.; one amino gp. and one sulfonamido gp. are bonded to carbon atoms of arom. nucleus the adjacent carbon atoms of which are not bonded to amino gp. and sulfonamide gp.) or a mixt. of an arom. diamine and said cpd. of formula I is reacted with a dibasic acid halide of formula II (wherein R is bivalent arom. gp.; X is halogen) to obtain polyamidosulfonamide which is then cyclized by dehydration to produce poly(amidobenzothiadiazine dioxide).
