抄録

The swelling phenomena of rubbers in oils and organic solvents are observed at the temperature from 30°C to 150°C. From these observed results, the diffusion constant and the μ constant are calculated by the Fick′s diffusion law and by the Flory′s swelling equilibrium formula.<br>The calculated diffusion constant values (D) of oils are about 10-9cm2/sec., and the values of organic solvents are about 1/100 of values of oils. The activation energy values of D are about 10kcal/mol in oils and about 5k cal/mol in organic solvents. The μ between oils and rubbers are larger than 1.5 in the case of NBR and larger than 0.5 in CR.<br>These calculated chemical constants are showed on tables.
