β¦ Synopsis
The properties of carbon residue derived from nitrogen-and phosphorus-containing polymer precursor were investigated by ESCA, gas adsorption and potentiometric titration. The carbon possesses N-, P-and O-containing functional groups. This functionality makes the surface hydrophilic and confers cation-exchange properties to the carbon. High thermal and chemical stability are the characteristic properties of the carbon.

Carbon-rich silicon oxycarbide ceramics were obtained by controlled pyrolysis at 950, 1300 and 1500 β’ C from hybrid polymeric precursors based on poly(methylsiloxane) and divinylbenzene with different molar ratios, in the presence or absence of nickel acetate. By increasing the pyrolysis temperature
A new type of epoxy resin, which contained phosphorus oxide and nitrogen groups in the main chain, was synthesized. The structure of the new type of epoxy resin was confirmed by infrared (IR) spectroscopy, 1 H nuclear magnetic resonance ( 1 H-NMR), and 13 C-NMR spectroscopic techniques. In addition,
