FIELD: chemistry.
SUBSTANCE: invention concerns polymerisation catalysts, particularly lactide polymerisation catalysts. Claimed metal compounds can be applied in chemical industry as catalysts, particularly for obtainment of biodegradable polymers (polylactides) applicable in food industry, medical technology, pharmaceutics etc. Invention claims catalyst for polylactide obtainment, including metal compound of the formula 
, where M is one of the following metals: Zn(II), Mg(II), Ca(II), Sr(II), Ba(II), Al(III), Ga(III), Ge(II); R1 and R2 are hydrocarbon substitute; R3 is alkyl, dualky, aryl or heterocycle; Y is oxygen or nitroge; X is a fragment of unsaturated C6-C22 hydrocarbon; S is present in the compound in some instances as coordinated solvent. Also invention claims method of polylactide synthesis by affecting lactide monomer by the claimed catalyst.
EFFECT: enhanced efficiency of catalyst.
