Abstract
Effect of pressure on the water absorption of general purpose unsatura ted polyester and vinyl ester resins was studied. The water absorption curves of polymers were determined at 25.5-degrees-C, 100% relative h umidity, and 1 atm. Polymers were immersed into 28.5-degrees-C water a t 1 atm and 1500 psi, respectively. The weight percent changes were ob served after 144 hours. The data of 1 atm and 1500 psi matched with th e weight changes of the sorption curves. The experiment indicated that no effect of pressure on water absorption of polyester and vinyl este r resins was found in this pressure range.
