Cross-linking and Tg | Practical Coatings Science | Prof ...
The equation assumes that you know the Tg at infinite MWt of "the" polymer without crosslinks. When in doubt assume that Tg ∞ is something like 50°C. It uses two constants, K 1 which you can assume to be ~50 and K 2 which, for good theoretical reasons, can be assumed to be between 0.5 and 1, with 0.8 being the default value.
