Abstract: 1. A PHOTOOXIDATION PROCESS FOR THE PREPARATION OF HYDROPEROXIDE DERIVATIVES OF POLYMERS HAVING A SATURATED POLYMER BACKBONE COMPOSED ONLY OF CARBON ATOMS AND HAVING C=C UNSATURATION LOCATED IN PENDANT GROUPS, SAID POLYMERS DERIVED FROM AT LEAST ONE MONO-OLEFIN AND AT LEAST ONE NON-CONJUGATED DIOLEFIN MONOMER, SAID PROCESS COMPRISING PHOTOOXIDIZING WITHOUT SUBSTANTIALLY AUTOOXDIZING SAID POLYMERS BY IRRADIATING SAID POLYMERS WITH LIGHT CAPABLE OF CATALYZING SAID REACTION AND OF A WAVELENGTHT OF 3000 TO 8000 ANGSTROMS IN THE PRESENCE OF AT LEAST A STOICHIONETRIC AMOUNT OF OXYGEN AND SENSITIZING AMOUNT OF A PHOTOSENSITIZER, WHEREIN THE CARBON ATOMS OF SAID C=C BONDS EITHER (A) CARRY TWO VICINAL CIS HYDROCARBON GROUPS WHICH DO NOT FORM PART OF ONE AND THE SAME CYCLIC SYSTEM, OR ELSE (B) CARRY AT LEAST THREE HYDROCARBON GROUPS, AND WHEREIN TRIPLET OXYGEN IS CONVERTED TO SINGLET OXYGEN.
