The linear PLAs and four-arm PLA with a similar chain length for each arm were synthesized by ring-opening polymerization. The linear and four-arm scPLAs were then prepared by solution blending and characterized by ¹H-NMR, FTIR, and WAXD analysis. Various mass ratios of the scPLAs were subsequently added to PLLA and PDLA as nucleating agents and specimens were prepared by solution casting. The isothermal and non-isothermal crystallization behavior of the specimens was examined by differential scanning calorimetry and polarized optRSC advancesInfluence of poly(lactide) stereocomplexes as nucleating agents on the crystallization behavior of poly(lactide)s.PMC906094651203118Li JHu GRen JJi NfalseInfluence of poly(lactide) stereocomplexes as nucleating agents on the crystallization behavior of poly(lactide)s.The influence of the addition of linear and four-arm poly(lactide) (PLA) stereocomplexes (scPLAs) on the non-isothermal and isothermal crystallization behavior of poly(l-lactide) (PLLA) and poly(d-lactide) (PDLA) from the molten state was investigated.
