  • Patent number: 6828270
    Abstract: The supported catalyst according to the present invention comprises a support of organic or inorganic powder with a high-surface area, a polymer coated onto the support and a metallocene catalyst. The polymer (1) contains polar groups; (2) interacts with the surface of the support; and (3) is insoluble in the styrenic monomer or polymerization solvent during polymerization after the catalyst is loaded. The polymer is located between the support and the metallocene catalyst such that the polymer insulates the metallocene layer from the support layer to prevent poisoning of the metallocene catalyst layer by the support layer. The styrenic polymer powder such produced by the present invention has good flow-ability and good morphology demonstrating a great deal of industrial applicability.

    Abstract: The present invention relates to a process of preparing syndiotactic styrenic polymers with a high conversion rate in the form of fine powder, which comprises (a) preparing styrenic polymers in a solid state by reacting a mixture consisting of styrenic monomers, a metallocene catalyst, a cocatalyst and inert organic solvent in a polymerization reactor, (b) separating a portion of the styrenic polymers from the reactor, (c) recycling the portion of the styrenic polymers in the reactor, and (d) reacting the recycled styrenic polymers with styrenic monomers. The styrenic monomers may include olefinic monomers. The monomers can be introduced to a single inlet or multiple inlets of the reactor. A single reactor or a plural number of reactors can be operated in the present invention. The plural numbers of reactors are arranged in series or in parallel. In the present invention, a self-cleaning mono- or twin-axis reactor can be employed to prevent the polymers from agglomerating on the inner wall or the axis.
