[edit] Production

Technora is produced by condensation polymerization of terephthaloyl chloride (TCl) with a mixture of p-phenylenediamine (PPD) and 3,4'-diaminodiphenylether (3,4'-ODA).[1] The polymer is closely related to Teijin's Twaron or DuPont's Kevlar. Technora is derived from two different diamines, 3,4'-ODA and PPD, whereas Twaron is derived from PPD alone. This relatively simple process uses only one amide solvent, and therefore spinning can be done directly after the polymer production.
