Abstract
We carried out thermal degradation of acrylonitrile-butadiene-styrene terpolymer (ABS), Nylon 6 (PA) and their mixtures in soybean oil at temperatures from 320°C to 360°C. In the mixtures, the decomposed effluent with low molecular weight increased quite markedly and the apparent activation energies of decomposition were smaller than those of the individual polymers. (ABS Ea= 61.3 kcal/mol, ABS 80/PA 20=41.6 kcal/mol, ABS 50/PA 50=27.3 kcal/mol and PA=86.0 kcal/mol.) The mixture of ABS and PA instantly degraded into oily products and oligomers of the polymers in soybean oil. The oil reacts with the polymers to speed solubility and decomposition.
