    摘要: The present invention is a process of preparing copolymers of vinyl aromatic and olefinic monomers wherein the polymerization is carried out in a dispersion in the presence of a metallocene catalyst and a dispersion aid. The dispersion aid is a styrene-diene two-block copolymer or a styrene-diene three-block copolymer. The resultant polymer is useful as a fiber, film or molding.
