ABSTRACT An emulsion or dispersion of a catalyst component in an inert liquid medium or an inert gas phase of a dispersion liquid phase, wherein the catalyst component is: (a) a compound of a transition metal from groups IV to VI which, in the liquid state, is immiscible with an aliphatic hydrocarbon, (b) a composi- tion comprising a compound as defined in (a) which, in the liquid state, is immiscible with an aliphatic hydro- carbon, or (c) a transformation product of a precursor of a compound as defined in (a) and a composition as defined in (b) which, in the liquid state, is immiscible with an aliphatic hydrocarbon. The emulsion or dis- persion is directly useable for the preparation of a coordination catalyst having a controlled morphology and/or a controlled particle size. The coordination catalyst polymerizes ethylene or a mixture thereof with another olefin to a polymer having controlled morphology and/or controlled particle size.
