Abstract

Invention concerns polymerization catalysts and especially catalysts for polymerization and copolymerization of lactide. The invented catalysts are based on metal complexes and can be used in industrial processes of manufacture of biodegradable polymers and copolymers, which in turn can be used as goods in the food industry, medicine, pharmacology etc. The catalyst for polymerization and copolymerization of lactide, comprising metal compound, represented by the general formula (I) where M - metal, selected from group Zn(II), Mg(II), Ca(II), Sr(II), Ba(II), Al(III), Ga(III), Ge(II) R1 and R2 - hydrocarbon radicals or substituted hydrocarbon radicals; R3 - one or two of alkyl, aryl or heterocyclic radicals; Y - heteroatom or carbon; X - fragment of hydrocarbon.
