Abstract
Aging of polyurethane films was studied using IR absorption and ATR sp ectroscopy, and mechanical tests. It was found that no degradation of the polymer occurs in the bulk of the material. Degradation of the mat erial proceeds at the surface of the samples under the action of atmos pheric oxygen, which leads primarily to the destruction of urethane gr oups.
