Abstract
The principles of the present invention are useful in telomerization reactions in which ethylene and/or propylene taxogen is used in free radical reactions to make telomers of limited molecular weight, e.g., those in which a major portion of the telomer products are telomers incorporating 1 to 12 moles of ethylene and/or propylene per mole of telogen (i.e., a major portion of the telomer products incorporate telomers for which n is 1 to 12). The present invention is based at least in part upon the discovery that using a very large stoichiometric excess of C1 to C12 telogen(s) (i.e., telogens incorporating 1 to 12 carbon atoms per molecule) in combination with using very low concentrations of initiator provides telomerization reactions that are selective for producing lower molecular weight telomers. In many embodiments, the present invention provides a product mixture of telomers in which a major portion of the product mixture contains telomers that incorporate 1 to 12, preferably 1 to 7, more preferably 1 to 5, even more preferably 1 to 3 moles of ethylene and/or propylene per mole of telogen.
