TGA/FTIR study of the catalytic pyrolysis of ethylene-vinyl acetate copolymers in the presence of MCM-41

The evolution of gas during the catalytic pyrolysis of three commercial ethylene-vinyl acetate copolymers in the presence of mesoporous MCM-41 has been studied by TGA/FTIR. The results have been compared with those corresponding to the thermal pyrolysis carried out under the same experimental conditions, and showed that the formation of alkenes and aromatics and shorter and/or more branched hydrocarbons is favoured in the presence of the catalyst.
