A polylactide is provided having a number average molecular weight of greater than 30,000 or a weight average molecular weight of greater than 60,000, wherein the proportion by weight in the molecular weight range up to 10,000 and in the molecular weight range above 500,000 is in each case from 5 to 15%. The polylactide may be prepared either by adding initiator during the production of the polymer in a plurality of portions at different times and/or at a plurality of locations if the process is carried out continuously or by using both a monofunctional initiator and a polyfunctional initiator or by carrying out the polymerisation in a continuous stirred reactor. |
