Abstract
A process for metalating a halogenated polyolefin so that only a very low percentage of the halogen originally present in the halogenated polyolefin is actually reacted during the process. The process comprises adding a solvated transmetalating organometallic compound to a cement mix of a halogenated polyolefin and a solvent. The transmetalating organometallic compound is present in the reaction in a molar amount less than the molar amount of the halogen content of the halogenated polyolefin. The reaction temperature is below 0.degree. C.
