AB - OF POLYPROPYLENE EFFECT OF AN IRON SALT ON OXIDATION UDC 542.943+541.64+547.313.3+546.72 L. L. Yasina, V. B. Miller, and Yu. A. Shlyapnikov Salts of metals of variable valence (iron, manganese, copper, etc.) accelerate the oxidation of hydro- carbons by molecular oxygen [I]. Some of these salts, particularly those of manganese, cobalt, and copper, simultaneously accelerate and retard oxidation, so that the dependence of the rate of oxidation on the salt concentration is complex. The literature apparently gives no information on the retarding effect of iron salts. EXPERIMENTAL The present paper deals with the oxidation of solid isotaetic polypropylene in the presence of an iron salt. Polypropylene was purified by the method in [2]. Anhydrous FeCI 2, obtained by roasting iron filings in a current of HCI [3], was added to an alcoholic solution of powdered polypropylene. Oxidation of poly- propylene was studied in a circulation apparatus [4] at 150 ~ in an atmosphere of dry oxygen (300 mm Hg). It will be seen from Fig. 1 that additions of FeCI 2 change the shape of the oxygen absorption curve. It is of interest that the curve plotting the maximum rate of oxidation versus the salt concentration has a minimum -
