摘要：
A process for removing catalyst residues from poly-1-butene which is disclosed which comprises contacting an organic phase containing the poly-1-butene dissolved in an inert hydrocarbon solvent with an aqueous solution of an alpha-hydroxysulfonic acid and then separating the poly-1-butene-containing phase from the aqueous phase.
