  • Is plasticization of PLA necessary?
  • The polymer is of interest for production of films for packaging applications. However, plasticization of PLA is required in order to obtain films with sufficient flexibility. PLA was blended with tributyl citrate (TbC) and two oligomers of TbC that were synthesized by transesterification of tributyl citrate (TbC) and diethylene glycol (DEG).
  • Which oligomeric plasticizers were prepared by transesterification of TBC and DEG?
  • Conclusions Two oligomeric plasticizers, one trimer (TbC-3) and one heptamer (TbC-7), were prepared by transesterification of TbC and DEG. The tertiary hydroxyl group on TbC seemed to have participated in the reaction, causing uncontrolled branching.
  • Can oligomeric plasticizers be used for PLA?
  • The study describes the synthesis of oligomeric plasticizers for PLA. The oligomers were based on tributyl citrate; a substance that had previously proven successful as a plasticizer for PLA , . The polymerization was performed as a transesterification reaction with diethylene glycol.
  • Does blending PLA with oligomeric plasticizers reduce glass transition temperature?
  • Blending PLA with the oligomeric plasticizers lowered the glass transition temperature. The plasticization effect was larger with low molecular weight plasticizers. TbC-3 was compatible with PLA at concentrations up to 20 wt% after which phase separation occurred.
  • How much TBC is present in PLA oligomer?
  • Both TbC-3 and TbC-7 contain approximately 10% of pure TbC, which means that 1.5 wt% pure TbC is present in a blend of PLA and 15 wt% oligomer. Thus, the depression of Tα caused solely by TbC would, according to previous investigations , , only amount to 1–2 °C which is far less than observed.
  • Is TG a function of plasticizer content?
  • Tg as a function of plasticizer content for blends of PLA with TbC, TbC-3 and TbC-7. The effects of blending PLA with TbC and TbC-3 can be compared with the results from a study where PLA was plasticized with PEG.
