ORGANOTIN COMPOUND, METHOD FOR PREPARING SAME, AND METHOD FOR PREPARING POLYLACTIDE USING SAME

摘要

The present invention relates to an organotin compound expressed as R1O-Sn-OR2 (where R1 and R2 are independent from each other, and both R1 and R2 are a primary, secondary or tertiary alkyl group having 5 to 30 carbon atoms), to a method for preparing the compound, and to a method for preparing polylactide using the compound. The organotin compound of the present invention can be easily prepared. When polylactide is prepared using the organotin compound, high molecular weight polylactide resins can be obtained at a high yield rate without using an initiator.
