PRODUCTION OF ISOTACTIC AND REGIORANDOM POLYPROPYLENE BASED POLYMER AND BLOCK COPOLYMERS

PRODUCTION OF ISOTACTIC AND REGIORANDOM POLYPROPYLENE BASED POLYMER AND BLOCK COPOLYMERS

One step ortho-alkylation of anilines with styrenes to give chiral anilines is obtained using a strong acid catalyst, e.g. CF3SO3H. Condensation of the product to give ligand and metallation gives complex which catalyzes polymerization of propylene to give isotactic propylene or regiorandom propylen...

Zusammenfassung:One step ortho-alkylation of anilines with styrenes to give chiral anilines is obtained using a strong acid catalyst, e.g. CF3SO3H. Condensation of the product to give ligand and metallation gives complex which catalyzes polymerization of propylene to give isotactic propylene or regiorandom propylene of low PDI or blocks thereof, depending on polymerization temperature.
