Improved process for the removal of catalytic residues based on AlCl3 and/or complex compounds thereof

摘要

Described is a selective process for the removal of catalytic residues based on AlCl3 or its complex compounds deriving from the (co)polymerization of olefinic and diolefinic cuts, allowing the production of almost colourless hydrocarbon resins. This process comprises contacting the polymerized mass with organometallic compounds, treating the resulting mixtures with water or aqueous solutions, either acidic or basic, and separating the organic phase, which at this point is without inorganic residues.
