Some relationships in the kinetics of preparing structurally-modified poly-m-phenyleneisophthalamide

-- The kinetics of the acylation of m-phenylenediamine and two chromophoric diamines — the sodium salt of 4,4'-diaminostilbenedisulfonic acid and 6-amino-2-(N-aminophenyl)benzoxazol used for chemical structure modification of fibre-forming poly-m-phenyleneisophthalamide has been investigated.
