Method for the removal of isobutene oligomers from an isobutene polymer |
| abstract |
A process is described for removing isobutene oligomers from an isobutene polymer by stripping the isobutene polymer with vapors of a saturated hydrocarbon having at least 8 carbon atoms and at least partly driving out the isobutene oligomers. Troublesome isobutene oligomers are substantially removed without impairing the reactivity of the isobutene polymer (expressed as the content of the methylidene double bonds). |
