Infrared temperature studies of a polyurea formed from 2‐methylpentane‐1,5‐diamine and 4,4′‐methylenebis(phenyl isocyanate) are presented, together with those of two model diureas, 2‐methylpentane‐1,5‐diphenylurea and ethylene diphenylurea. The main thrust of the work concerns the interpretation of the infrared changes that are observed in ordered and disordered hydrogen bonded ureas.
