For various epoxy resins, the suppression of Tg in °C can be approximated by the expression (reduced from data presented by Wright 1981) 

Data for fluid expansional coefficient jS are listed in Table 4.4. 

Moisture distribution profiles during transient states were measured by two distinct techniques. One method utilized exposure to radioactive deuterium (D2O), in which case total weight-gain data were indiscernible from those for H2O, and distributions
