Synthesis and characterization of condensed poly-nuclear aromatic resin using heavy distillate from ethylene tar
Source abstract
Abstract
Heat-resistant condensed poly-nuclear aromatic resin (COPNAR) was prepared using heavy distillate (>250 °C, named DO) from distilled ethylene tar (ET). The basic properties of ET, DO and COPNAR were investigated by FT-IR, 1H-NMR, TGA and elemental analysis. The structural parameters of DO and ET were obtained by the improved Brown – Ladner method and the formation mechanism of the COPNAR from DO was deduced. Results show that a superior heat-resistant COPNAR can be obtained from DO. The distillation of ET increases the heat resistance of the COPNAR, and the reaction mechanism is confirmed to be an acid-catalyzed positive ion-type polymerization.
