All-polymer composites – a new approach with the use of disentangled semi-crystalline polymers
Part I. Disentangling and properties of disentangled polylactide (in English)
Polimery 2020, No 3, 167
This contribution discusses the preparation of partially disentangled polylactide from solution. The rheological method determined how the density of macromolecular entanglement depends on the concentration of the prepared solution. From a 0.1 wt % solution, the polymer having 20% of the original entanglements was obtained. The crystallization studies in isothermal conditions showed that the growth of crystals can be 10% faster if the polylactide is partially disentangled. For the first time, it was shown that in the partially disentangled polylactide there are shifts in temperatures of crystallization regimes.
