Terminally unsaturated polymer, particularly isobutene polymer production for producing fuel and lubrication material additives involves carrying out dehydrohalogenation of polymer in presence of solvent

摘要

Terminally unsaturated polymer production involves carrying out dehydrohalogenation of a polymer in presence of a solvent. The polymer has an endgroup of general formula (I), and the average molecular wt. of the polymer is 500-5000. General formula (I) is, -CH2-C+>(CH3)2 Hal-> In formula (I), Hal : halide ion or a complex halide ion.
