Ah&act-Surface acidity of charcoals prepared by the carbonisation of PVDC, PVC, Saran, PF and UF polymers has been determined by titration with sodium hydroxide and sodium ethoxide. The surface acidity as determined by titration with 0.2N sodium hydroxide solution is found to be almost exactly equiv

## Carbons have been prepared by pyrolysis of polymers at 7OO"C, and subsequent heating to 1500,2000,2700 and 3000Β°C. The specific surface areas and the densities in mercury, helium and, in some cases, carbon tetrachloride, have been determined. The open pore volume of non-graphitizing carbons dec
Interaction of poIymer charcoais with bromine in aqueous sofutions results in the conversion of bromine into HBr and its fixation by the charcoals. The amount of bromine converted into HBr is related to the surface acidity of the char while the amount fixed depends upon the nature of the char and th
