Aromatic processable poly(amide-imide)s have been prepared according to the Yamazaki and Higashi phosphorylation reaction from flexible aromatic diamines and a mixture of isomeric 1,2,4-benzenetricarboxylic acid monoethylesters following a novel "one-pot'' procedure. The polymerization was performed
## Abstract Four dicarboxylic acids containing one preformed imide ring were prepared by condensation of trimellitic anhydride with α‐amino acids such as glycine, DL‐alanine, DL‐valine, and DL‐lcucinc. These diacids were subsequently directly polycondensated with various aromatic diamines using tri
Pentyloxyterephthalic acid was prepared by alkylation of dimethyl trimethylsiloxyterephthalate with (S)-2-methylbutan-l-o1 tosylate. (S,S)-2,5-bis-i-pentyloxyterephthalic acid was prepared analogously by alkylation of diethyl-2,5-bis(trimethylsiloxy)terephthalate. A series of cholesteric poly(ester-
