Lifetime spectra of positrons have been measured for acrylic epoxy-based network polymers. For the specimens with the different permeability coefficients to water vapor C p , the lifetime of ortho-positronium (o-Ps) 3 increased with increasing C p . This fact suggests that the permeability increases
