Reaction Steps

U.S. Pat. No. 3,671,542 also describes that a copolyamide from p-phenylenediamine+4,4'-diaminobenzanilide (1:1) and terephthaloyl chloride+dibenzoyl chloride or 2,6-naphthaloyl chloride (1:1) becomes gel-like in amide solvents within a short period of time. The properties of the filaments (spun from sulfuric acid) are moderate. Only a 6-component polymer from (p-phenylenediamine+1,5-diaminonaphthalene+4,4'-diaminobenzanilide) and (terephthaloyl chloride+2,6-naphthaloyl dichloride+dibenzoyl chloride) gives a homogeneous solution in amide solvents. The properties of the filaments spun from sulfuric acid are moderate.
