2. Solubility Parameters (δ) of PLA, GT, and DINCH Calculated Using the Hoftyzer–Van Krevelen Method,

Material	δ_d (MJ/m³)^1/2	δ_p (MJ/m³)^1/2	δ_h (MJ/m³)^1/2	δ (MJ/m³)^1/2
NR	17.70	0.00	0.00	17.70
ENR	13.90	2.42	4.26	14.74
GT	15.20	6.33	8.61	18.94
TOTM	16.75	2.86	6.17	18.07
Sulfur	33.10	0.00	0.00	33.10

The δ_d, δ_p, and δ_h contributions were used to determine the solubility parameters for each component.
