For six epoxide-amine systems, based on mixtures of two different aromatic epoxides with four various aromatic amines, the solubility parameters S were determined by calculation, by using several literature sources and molar additive laws, and experimentally from equilibrium concentrations of 25 solvents, by using bidimensional solubility maps. 6 values ranging from 20 to 27 MPd" were found. Their variations with the epoxide and amine structure were discussed. The crosslink density was found to have a neglectable effect on the solvent absorption compared to interaction parameters.

## Abstract As generally accepted, also in the case of polyamides linear and crosslinked polymeric materials are believed to be characterized by the same solution properties and, consequently, by the same solubility parameters. However, despite their great practical importance, a thorough study aim
