Abstract
Process for the purification of high molecular weight and linear copolymers of alpha-olefins, each other and/or with other unsaturated hydrocarbons, obtained by the method described above, which process comprises emulsifying, in one or more phases, a solution of the copolymer in a hydrocarbon solvent with an aqueous solution of a mineral acid capable of dissolving the catalyst residue, allowing the emulsion to separate into two layers, of which the aqueous layer is separated, and subsequently emulsifying the other layer with pure water in a sufficient to eliminate the anion of the acid used.
