Dihydrocarbon peroxides capable of controlling polymerization reactions

Claim 1

A PROCESS FOR THE POLYMERIZATION OF AN UNSATURATED POLYMERIZABLE ORGANIC COMPOUND SELECTED FROM THE GROUP CONSISTING OF COMPOUNDS CONTAINING ETHYLENIC UNSATURATION AND COMPOUNDS CONTAINING ACETYLENIC UNSATURATION, WHIC COMPRISES SUBJECTING SAID COMPOUND TO POLYMERIZATION REACTION CONDITIONS IN THE PRESENCE OF A POLYMERIZATION CONTROL AGENT COMPRISING A PEROXIDE OF A HYDROCARBON HAVING THE FOLLOWING GENERAL STRUCTURE: WHEREIN R AND R1 TO R7 ARE SELECTED FROM THE GROUP CONSISTING OF HYDROGEN, ALKYL, ALKENYL AND ALKAPOLYENYL HYDROCARBON RADICALS, AT LEAST TWO OF THE GROUP R3 TO R7 BEING HYDROCARBON RADICALS AND NOT MORE THAN TWO OF THE GROUPS R, R1, R2 AND R7 BEING HYDROGEN, SAID HYDROCARBON HAVING A MOLECULAR WEIGHT OF FROM ABOUT 250 TO ABOUT 1000 AND CONTAINING FROM ABOUT 2.5 TO ABOUT 4 DOUBLE BONDS PER MOLECULE OF WHICH AN AVERAGE OF FROM ABOUT 1.5 TO ABOUT 2.5 BELONG TO A CONJUGATED DIENIC SYSTEM AND THE REMAINING OLEFINIC LINKAGES ARE DISTRIBUTED THROUGHOUT THE HYDROCARBON CHAINS IN ISOLATED POSITIONS.
