Table 2.

Glass transition temperatures (Tg), enthalpy of cold crystallization (Δhc), enthalpy of fusion (Δhm), and crystalline weight fraction growing during cold crystallization (wCc) and disappearing during fusion (wCm) for PLA and PLA mixed with (1) ATBC and (2) ATBC and the mineral filler CaCO3 (estimated errors: ± 0.5 °C for Tg; ± 1 J/g for Δhc and Δhm, and ± 0.02 for wCc and wCm).

Tg (°C) Δhc (J/g) wCc Δhm (J/g) wCm
PLA 58 24 0.24 28 0.24
[PLA (90 wt%) + ATBC (10 wt%)] 50 27 0.28 33 0.28
[PLA (85 wt%) + ATBC (10 wt%) + CaCO3 (5 wt%)] 50 27 0.28 33 0.28
