## Abstract A novel monomer diacid, 6,6′‐methylenebis(2‐oxo‐2__H__‐chromene‐3‐carboxylic acid), was synthesized and used in a direct polycondensation reaction with various aromatic diamines in __N__‐methyl‐2‐pyrrolidone solution containing dissolved LiCl and CaCl~2~, using triphenyl phosphite and p
High molecular-weight aromatic polyamides were obtained from 1,5-and 2,6-bis-(4'-carboxy-4-phenylenoxy-sulfony1)naphthalene by direct polycondensation reaction in N-methyl-2pyrrolidone with various aromatic diamines, using triphenyl phosphite and pyridine as condensing agents. The polymers were char
## Abstract Disulfide‐functionalized hyperbranched poly(amido amine)s (HPAMAMs) were synthesized by Michael addition polymerization of __N,N__'‐cystaminebisacrylamide and 1‐(2‐aminoethyl)piperazine. The novel HPAMAMs displayed bright fluorescence, and the emissions bands cover nearly the whole visi
