Abstract

Characteristics of pyrolysis and liquid product distribution of ABS plastics have been studied in the thermogravimetric(TG) reactor and bomb microreactor. Pyrolysis reactions were performed at temperature $400\sim450^{\circ}C$ and yield of each pyrolytic product was obtained by the weight measurement method. The molecular weight distributions of liquid products were determined by the GC-SIMDIS method. It was observed that solid residue which could not be detected in the thermogravimetric experiments was significantly formed in the batch-type microreactor. It was found that the yield and average molecular weight of liquid products were decreased with the increase of reaction temperature and time. but the formation of styrene monomer was significantly increased. The chain-end scission rate parameters were determined to be 54.1kcal/mole far ABS by the Arrhenius plot.
