Glass transition temperatures (Tgs), heats of fusion and crystallization and specific heats in the solid phase, for a series of statistical copolyamides (nylon-8/nylon-12), prepared by activated anionic polymerization of octane-/laurolactam (OL/LL), were determined and the results were correlated with the molar composition of the copolyamides and discussed. Minima for Tg and the heat of fusion for the initial melting and maxima for Tg/initial melting point (Tin) and changes in specific heat values were indicated for copolyamides with 50/50-60/40 molar compositions.
