sci.Fox-equation-glass-transition Calculator
Calculates the glass transition temperature of a copolymer or blend from the Fox equation: 1/Tg = w₁/Tg₁ + w₂/Tg₂. The Fox equation assumes ideal mixing — deviations indicate specific interactions between components (e.g., hydrogen bonding elevates Tg above prediction).
Inputs
Phi1 Pct
Body or object weight. For health calculators, usually in kg or lbs.
Tg1 K
Reference formula or conversion factor shown for context.
Tg2 K
Reference formula or conversion factor shown for context.
Results
blend Tg (Fox equation, K)
The value at the specified point or condition.
blend Tg (°C)
Sample size or count used in the calculation.
linear mixing rule Tg (K)
Sample size or count used in the calculation.
plasticization ΔTg from pure Tg1
The value at the specified point or condition.
1/Tg = w1/Tg1 + w2/Tg2
Reference formula or conversion factor shown for context.
