<p>A process for adjusting the melt flow of an olefin polymer product during a polymerization reaction comprising the polymerization of at least one alpha olefin in the presence of a polymerization catalyst, polymerization cocatalyst, and hydrogen as a molecular weight control agent, characterised by reacting at least part of the hydrogen with at least part of the alpha olefin in the presence of a hydrogenation catalyst when it is desired to reduce the melt flow of the polymer product.</p> |
