Abstract (en)

[origin: WO9920449A1] The present invention is directed to injection-molded articles prepared from a composition comprising a long chain branched syndiotactic mononvinylidene aromatic polymer. Long chain branches can be produced during polymerization by polymerizing in the presence of a small amount of a difunctional monomer.
