Abstract: A process for the production of an essentially syndiotactic and partially crystalline polymer (I) containing vinyl aromatic monomers is claimed. (I) is prepared form a reaction mixture containing vinyl aromatic compounds (II), metallocene complexes (III) and one or co-catalysts (IV) consisting of strong, neutral Lewis acid or Bronsted acid cations. The components are mixed prior to addition to the reactor. An apparatus is also claimed comprising a reservoir to contain a mixture of (II) and (IV), a reservoir to contain (III) plus means to dose the contents of the 2 reservoirs to a pre-mixer that is connected to the reactor vessel.
