Effect of deuterium on polystyrene degradation
The effect of replacing hydrogen by deuterium in polystyrene was studied on resistance to oxidative and thermal degradation. Polystyrene, polydeutero-styrene-D/sub 8/ containing 98-99 at.% deuterium, and a series of their statistical copolymers containing various proportions of deuterated and undeuterated monomer units were synthesized. The replacement of hydrogen by deuterium in polystyrene caused some increase in its resistance to thermal and oxidative destruction. A table shows that at all test temperatures, an increase in the fraction of deuterated monomer units in copolymer decreases the amounts of absorbed oxygen and evolved carbon oxides which is evidence for retadation of polystyrene oxidation when hydrogen is replaced by deuterium.
