抄録

Thermosetting resins named COPNA resin were prepared by heating polycondenced armotic compounds (Aro) with 1, 4-benzenedimethanol (PXG) and p-toluensulfonic acid as a catalyst. Aro used were pyrene/phenanthrene (7/3 in molar ratio) mixture (PP), napth-alene and coal-tar pitch. The COPNA resins were heat-treated between 200 and 2500°C to examine their carbonization behaviors. Major/results obtained are:<BR>(1) The COPNA resins derived from PP or naphtalene with an amount of PXG above 1.0 in PXG/Aro molar ratio decomposed first thermally around 450°C. Thus, the methylene bridges in the COPNA resins were broken down around 450°C. The pitch-based COPNA resin exhibited the weight loss over a wider temperature range.<BR>(2) Carbon yields from the COPNA resins increased with both increasing, molecular weight of raw Aro and the cross-linkage density. They were 38 and 60 wt% for the naphthalene (PXG/Aro=1.25 in molar ratio) based-and the pitch (PXG/Aro=2.0 in molar ratio) based-COPNA resins respectively. The PP-based one showed an intermediate value between them.<BR>(3) The COPNA resins after heating to 2500°C gave X-ray parameters corresponding to those for the non-graphitizable carbon. hitizability of those resins improved with the increasing molecular weight of Aro and/or the decreasing molecular ratio of PXG/Aro.
