Synthetic Metals, 1991
Abstract Composite fiber of poly(paraphenylenediamine) (PPD)-terephthalic acid (T), the polymer for Kevlar ®+ aramid, and emeraldine salt (ES) of polyaniline was prepared by mixing emeraldine base polymer in PPD-T/H 2 SO 4 spin dope and extruding it into fibers. The typical fiber diameter is ∼ 25 microns.

Occurrence of p-phenylenediamine antioxidants (PPDs) and PPDs-derived quinones in indoor dust
Science of The Total EnvironmentThe p-phenylenediamine antioxidants (PPDs) have been widely detected in various dust samples. Nevertheless, the knowledge on occurrence of their environmental transformation products, PPD-derived quinones (PPDQs), in indoor dust remains limited. In this study, indoor dust samples (n = 97) were collected from Hangzhou, China, and analyzed for PPDs and ...
