✦ Synopsis

The effect of water immersion at 70Β°C on undercured epoxy thermosets obtained from tris [ 4-(2,3-epoxypropoxy)phenyl] methane and 4,4'-diaminodiphenylsulphone and from N,N-bis (2,3epoxypropyl) aniline and 1,3-diaminobenzene was investigated. It is concluded from water absorption studies, Tg measurements, and gravimetric data that the predominant reaction is that of additional cure induced by the plasticising and catalytic effect of the absorbed water.
