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.

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
