✦ Synopsis

The thermal expansion of modified epoxy resins was investigated from 4.5 to 293 K with a highly sensitive capacitance dilatometer. The samples were made from diglycidyl ether modified with diols of different chain lengths. Increasing the diol chain length increases the thermal expansion coefficient. At temperatures lower than 40 K, expansion is determined only by the binding forces between the epoxy chains.
