Beschreibung
Zusammenfassung:The invention discloses a methyl aluminum complex of a tetradentate nitrogen-oxygen ligand and application thereof. The structural formula of the complex is disclosed as Formula I, wherein R is hydrogen or halogen. The complex can implement N, N, O and O tetradentate coordination, and has the advantages of special structure, simple preparation method and excellent properties. The complex can be used as a catalyst for lactide ring-opening polymerization reaction, has the advantages of high catalytic activity and high reaction rate, can regulate the three-dimensional structure and molecular weight of the polymer, and can obtain products with different molecular weights in a controllable way. The molecular weight of the prepared polymer can be 2000-170000; and thus, the complex has wide selectivity and favorable market prospects.
