The thermal properties of some new higher molecular weight UV absorbers of the 2‐hydroxy‐benzophenone type have been studied using DTA and TG methods, and the obtained results have been compared with the thermal properties of 2‐hydroxy‐4‐ n ‐octyloxybenzophenone. The DTA, TG, and DTG curves and initial and maximum rate temperatures are given. The maximum rates of active decomposition and residues were also evaluated.
