Abstract
The ansa-metallocene complex (CpCMe2Flu)Nd(C3H5)(THF) (1) is an effective single-component catalyst for the production of syndiotactic styrene-rich polymer materials modified by isoprene and/or ethylene. The recovered copolymers have high molecular weights (Mn = 12,000-91,000 g/mol) and unimodal, relatively narrow molecular weight distributions (Mw/Mn = 1.3-2.8). The comonomer feeds can be easily manipulated to tune the respective amounts of monomers incorporated in the copolymer and eventually modify the final properties (Tm, Tg) of the obtained materials.
