Organometallic catalyst for production of resorbable biocompatible polymer, e.g. polylactic acid

The organometallic catalyst for the production of a resorbable biocompatible polymer has the general formula (I) AnMBm(H2O)p (I) in which M = an atom of a metal with free p, d or f orbitals; A = a hydroxyacid -O-CO-R-OH in which R = 1-18 C alkyl; B = a hydroxyacid or -OR' in which R' = H,...
