METHOD OF TELOMERIZING ETHYLENE WITH OLEFINIC HYDROCARBONS WHICH COMPRISES CONTACTING ETHYLENE AT A TEMPERATURE IN THE RANGE OF 50-180*C. WITH A NONAROMATIC, NON-CONJUGATED OLEFINIC HYDROCARBON CONTAINING AT LEAST ONE ALLYLIC HYDROGEN ATOM IN THE PRESSENCE OF A CATALYST PREPARED BY COMBINING A NON-AROMATIC TERITARY AMINE WITH LIR WHEREIN R IS A HYDROCARBON RADICAL HAVING 1-30 CARBON ATOMS SELECTED FROM THE GROUP CONSISTING OF ALKYL, CYCLOALKYL, ARYL, ARALKYL AND ALKENYL, AND SEPARATING FROM THE REACTION MIXTURE A TELOMERIZATION PRODUCT EACH MOLECULE OF WHICH CONTAINS ONLY ONE MOIETY DERIVED FROM SAID NON-AROMATIC, NON-CONJUGATED OLEFINIC HYDROCARBON.
