Summary:A process for preparing syndiotactic polymers of vinylaromatic monomers having improved melt flowability comprising contacting one or more vinylaromatic monomers with a catalyst system comprising a titanium coordination complex capable of preparing syndiotactic vinylaromatic polymers under addition polymerization conditions in the presence of hydrogen gas at a hydrogen partial pressure from 0.1 to less than 10 kPa.
