We compared the cross‐polymerization of diacetylene units, incorporated in different ways into polyamide (PA) matrices: as fragments of the PA main chains (PA1) and as pendant groups of the PA main chains (PA2). At room temperature the reaction proceeds only in PA1 via 1,4‐addition (cross‐links I). However at high temperature besides of cross‐links I another type of cross‐links (cross‐links II) is formed, presumably via 1,2‐addition reaction. In PA2 only cross‐links of type II are formed at high temperatures.
