Abstract

The invention relates to a method for the production a biodegradable polymer of cyclic esters in particular for medical applications. The method is carried out by bulk polymerization with the catalysts, wherein the catalysts are Lewis acids partially blocked by Lewis bases. According to the method the Lewis acids are compound of elements selected from the Group IIB, IIIB, IVA and IVB of the Periodic Table.
