Abstract

Polyurethanes used for thermal barrier applications in the window industry were exposed to a variety of aqueous treatments to simulate long-term field weather conditions. The mass change of these polyurethanes due to absorption ofvarious solutions was monitored and diffusion equations proposed. Test specimens were also evaluated for changes in physical properties (i.e., tensile strength, elongation, and izod impact) resulting from exposure to these treatment groups. To determine if changes in these physical properties should be attributed to chemical degradation from hydrolysis, or entrapment of treatment solutions within the polyurethanes, samples were analyzed via attenuated total reflectance infrared spectroscopy (ATR-IR).
