摘要：

Theoretical aspects of the diffusion of small molecules in elastomeric polymer membranes are explored using a Monte Carlo simulation to estimate the free volume fraction in two typical siloxane elastomers. The model took into account the specific chemical structure of the polymer through the rotational isomeric state approximation. Calculated results for the two polymers agree semiquantitatively with experimentally determined diffusion coefficients. © 1990, American Chemical Society. All rights reserved.
