A simple scheme for the prediction of glass transition temperatures based on diamine and diacid component part contributions is applied to data for 19 interrelated polyamides. The new results, in conjunction with many prior determinations, lead to the assignment of 65 ± 20°C. for the glass transition of 6‐6 polyamide, contrary to published suggestions that the value might well be −65°C.
