The following work concerns with the carbonisation polyacrylonitrile and polyethylene te¬rephtalate mixtures of different compositions. Polyacrylonitrile originated carbons predominate in the corbonisation products of the mixtures containing more than 30 % of this polymer. The increasing proportions of polyacrylonitrile increases carbonisation yield. Ali carbonisation pro- duct give BET Type-I adsorption isotherms. Activation to 30 % burn-off increases the adsorp- tion capacity while further activation decreases. At low polyacrylonitrile concentrations adsorp¬tion and activation characteristics are determined by polyethylene terephtalate.
