A PROCESS FOR PRODUCING HIGHER HOMOLOGUES OF ORGANIC TELOGENS CONTAINING ONLY ATOMS SELECTED FROM THE GROUP CONSISTING OF CARBON, HYDROGEN, BORON, HALOGEN AND OXYGEN AND HAVING A LABILE HYDROGEN ATOM, WHICH COMPRISES ADDITION-TELOMERIZING THE TELOGEN WITH FROM ABOUT ONE TO ABOUT TWO MOLES PER MOLE OF AN UNSATURATED TAXOGEN HAVING THE FORMULA CR1R2=CH2, WHEREIN R1 AND R2 ARE SELECTED FROM THE GROUP CONSISTING OF HYDROGEN, AND ALIPHATIC AROMATIC, AND CYCOALIPHATIC RADICALS HAVING FROM ABOUT ONE TO ABOUT SIXTEEN CARBON ATOMS IN A MOLAR PROPORTION OF ORGANIC TELOGEN:TAXOGEN OF FROM ABOUT 100:1 TO ABOUT 100:1 IN THE PRESENCE OF A FREE RADICAL INITIATOR CAPABLE OF INITIATING THE TELOMERIZATION AT A TEMPERATURE BELOW THE BOILING POINT OF THE TELOGEN AND AT WHICH AN EVOLUTION OF FREE RADICALS FROM THE INTIATOR IS OBTAINED.
