Thermal-and photo-stabilities of unstabilized acrylonitrile-butadiene-styrene terpolymer, ABS, have been investigated by i.r. spectroscopy. Degradation of ABS samples is initiated by attack on the polybutadiene (PB) component; oxidation products containing hydroxyl and carbonyl groups are produced.

Thermal degradation of ABS and denitrogenated ABS samples (DABS), prepared by sequential hydrolysis of ABS using PEG/NaOH, has been investigated under inert gas and at atmospheric pressure in a temperature range between 40 and 700 β’ C, by means of TGA, TGA-IR, and TGA-MS, to study the link between o
Abs~'act--The mechanisms of thermal and photo-oxidative degradation of unstabilized samples of ABS have been discussed in terms of the known chemistry of the unsaturated isomeric units of PB and the chemical species identified by either i.r. spectroscopy or chemical studies. The reactions which lead
