Abstract: Method for separating ionic liquid from non-polar liquid mixtures comprising non-polar solvents as main components, ionic liquids and optionally other ingredients, where the weight ratio of ionic liquids to the non-polar solvent is less than 1:1000, comprises adsorbing the ionic liquid in an inorganic oxide carrier materials. An independent claim is included for a method for the preparation of homo- or co-polymer with a molecular weight of 10000-10000000 from a monomer with one or two polymerizable olefinic unsaturated double bond that comprises 3 or 4 carbon atoms and a desired comonomer with one or more polymerizable olefinic unsaturated double bond that comprises 3 or 30 carbon atoms and same or different monomers comprising polymerization or copolymerization of these olefinic monomers and/or olefinic monomer containing monomer mixture in liquid phase in the presence of non-polar solvent and at least one ionic liquid as polymerization catalyst, where after the polymerization, the ionic liquid is separated by adsorption on the inorganic oxide carrier material.

Abstract: Reducing adhesiveness of a molded body from polymer, comprises contacting polar solvents on the surface of polymer in the absence of non-polar solvent, where the polar solvent is hydroxylgroup containing compound, and/or carbonylgroup containing compound, and the polar solvent do not contain non volatile salt-like or polymer character ingredients; and gluing an essential portion of the polar solvent and/or their mixture on the surface of the molded body. Reducing adhesiveness of a molded body from polymer, comprises contacting polar solvents on the surface of polymer in the absence of non-polar solvent, where the polar solvent is hydroxylgroup containing compound of formula (R1>-(O-A)n-OH), and/or carbonylgroup containing compound of formula (R2>-CO-X-R3>), and the polar solvent do not contain non volatile salt-like or polymer character ingredients; and gluing an essential portion of the polar solvent and/or their mixture on the surface of the molded body. R1>, R2>2-20C alkyl, 2-20C alkenyl, 5-20C cycloalkyl, 6-20C aryl, 20C alkylaryl or 20C arylalkyl; A : 2-4C alkylene; n : 0-10, preferably 0; X : O, S or chemical bond (if R2> is not hydrogen); and R3>1-20C alkyl, 1-20C alkenyl, 5-20C cycloalkyl, 6-20C aryl, 6-20C alkylaryl or 6-20C arylalkyl.
