Abstract The very early stages of the oxidation of polymers at ordinary temperatures must be studied if the ultimate reasons for oxidative instability are to be discovered. To this end apparatus which will allow the absorption of small amounts of oxygen to be measured with high precision has been designed and built. Its design is such that both photoinitiated oxidation and pure photolysis may be studied. Experimental manipulation of the apparatus and the calculation of results are discussed, as well as the preparation of polystyrene films for photooxidation and photolysis investigations.
