Abstract

It is shown that single-photon counting capability is not the necessary condition for successful application of chemiluminescence in polymer research. The instrument that measures integral photocurrent and utilizes proper methodology can be efficiently employed, even in evaluation of such low-emitting compounds as vulcanizates containing 40phr of carbon black. The usefulness of the technique is demonstrated for a variety of elastomeric systems: unvulcanized and vulcanized compositions as well as formulations with fillers and antioxidants. Numerous examples of good correlation between chemiluminescence and differential scanning calorimetry are presented. ©
