Solid-state polycondensation (SSP) as a method of obtaining high molecular weight polymers. Part 2. Synthesis of polylactide and polyglycolide via SSP
Izabela Steinborn-Rogulska , Gabriel Rokicki
AbstractSolid-state polycondensation (SSP) is a competitive method of semicrystalline polymers synthesis to conventional melt polycondensation process. The molecular weight of polymers obtained according to this method is exceptionally high and the process can be carried out under milder conditions than those of the melt state. In this method the side reactions are suppressed, especially those leading to the polymer degradation. In this paper, which is a continuation of our previous publication, the application of solid-state polycondensation method for obtaining high molecular weight polylactide and polyglycolide – polymers of high importance for medicine and the environmental protection - is presented and discussed. The two-phase model according to which polycondensation proceeds in the amorphous regions, and the apparatus usually used in this process are also described.
