<p>Styrenic polymer is produced by polymerisation of styrene monomer in the presence of a filler and using a catalyst consisting of (1) a titanium compound and (2) an aluminoxane (pref. methylaluminoxane). The product is pref. of syndiotactic structure. The filler acts as a carrier for the catalyst and is pref. 1-85% (wt.) of the total composition; specifically claimed fillers are carbon black, copper, phthalocyanine green, calcium carbonate, silicon carbide, talc, mica, silica, glass fibre and C fibre.</p> |
