ABSTRACT:
Liquid perfluoroalkyl iodides are added to non-halogenated gaseous olefins or non-halogenated acetylenes in the presence of free radical generating catalysts to produce an additive reaction product essentially free of telomers. The gaseous olefin or acetylene is bubbled through liquid perfluoroalkyl iodide and catalyst at temperatures of 40.degree. to 220.degree. C and pressures no higher than atmosphere. Illustratively, ethylene is added to 1-iodoperfluoroheptane in the presence of benzoyl peroxide.
