| titleOfInvention | Schiff base aluminum compound, preparation process of Schiff base aluminum compound and preparation process of polylactic acid |
| abstract | The invention provides a Schiff base aluminum compound, a preparation process of a Schiff base aluminum compound and a preparation process of a polylactic acid. The structure of the Schiff base aluminum compound is represented as formula (I). When the process is compared with single metal-centered Schiff base of the prior art, a tetramine compound is connected with four C=N functional groups, so that two metal active center binding sites are provided, and double metal-centered Schiff base can be formed. The double metal-centered Schiff base has a large molecular space, so that the high steric hindrance is obtained, the selectivity for lactide ring-opening polymerization is enhanced, and the regularity of polymerisate space structures is improved; and the introduction of double metal centers also improves the reactivity of catalysts, and the activity of polymerization reactions is improved. |
