摘要：

Acetone and propene oxide were mixed with equal volumes of Maraglas epoxy embedding medium. Retention of these solvents in the resin after cure at 60 C was measured. The retention of propene oxide was greater than that of acetone and appeared to be due to a chemical interaction with the monomer. The reaction was catalysed by benzyldimethylamine. Although 3-4% of added acetone was retained, no evidence that this resulted from a chemical interaction was obtained. Vacuum evacuation of added solvents prior to cure did not materially affect their retention. Retention of both solvents resulted in softer cured resins. © 1969 Informa UK Ltd All rights reserved: reproduction in whole or part not permitted.
