The thermally induced solid‐state polymerization of 66 nylon was investigated. It was found that the rate‐controlling step in the process is chemical reaction. A mechanism of the form, rate = kt n was shown to hold. The reaction rate constant was found to be k = 1.53 × 10 10 exp [ − 12,960/ RT ]. Units of k are (hours) −0.51 . Activation energy determined in this work compared closely to that determined for nylon 6 solid‐state polymerization.
