A process for removal of a catalyst from a polymerization reaction mixture, comprises adding at least one polar solution to the reaction mixture to form a first at least two phase mixture, wherein one phase of the first at least two phase mixture is a first polymer phase; liquid/liquid centrifuging the first at least two phase mixture to separate the phases; removing the first polymer phase from the first at least two phase mixture; adding water to the first polymer phase to form a second at least two phase mixture, where one phase of the second at least two phase mixture is a second polymer phase; and separating the second polymer phase from the second at least two phase mixture.
