Carbonization process of resol phenol formaldehyde resin-polyvinyl butiral copolymer is discussed. Gaseous products of pyrolysis were analyzed by means of GC/MS. These data along with data from periodic sources were used to offer probable scheme of pyrolysis process of this copolymer. Kinetic parameters of the process were obtained from dynamic thermogravimetric measurements. The parameters were used to calculate constant mass loss rate temperature program. BET areas and pore size distributions of samples prepared using constant heating rate and constant mass loss rate temperature programs were calculated from nitrogen adsorption isotherms.
