| titleOfInvention | PROCESS FOR PRODUCING PLLA / PDLA STEREOCOMPLEXES |
| abstract | A production process for obtaining a 40-60 / 60-40 PLLA / PDLA stereocomplex polymer of number average molecular weight of at least 15,000 Dalton comprising bulk polymerization of LL Lactide to form PLLA, polymerization in mass of DD Lactide to form PDLA then the mixture, in the absence of solvent, of the two polymers obtained previously in proportions of 60-40 / 40-60 in the presence of the initial catalytic system used during the polymerization of PLLA and PDLA and optionally in the presence of L-Lactide and unconventional D-Lactide at a temperature above the melting point of the PLA without exceeding the temperature of 250 ° C. The stereocomplex polymer of PLLA / PDLA thus obtained is stabilized, if necessary demonomerized, then granulated. |
