The fourth edition of this reference work provides comprehensive and current information on material weathering for over forty families of polymers, which can dramatically reduce time used searching for answers in many different sources. It presents discussions on formulating mechanisms of degradation, effect of thermal processes, present characteristic changes in properties, and tables of available numerical data.

Contents include: Photophysics, Photochemistry, Parameters of Exposure, Measurements in Assessment of Weathering Conditions, Climatic Conditions, Methods of Outdoor Exposure, Laboratory Degradation Studies, Weathering Cycles, Sample Preparation, Weathering Data Interpretation & Lifetime Prediction, Artificial Weathering versus Natural Exposure, Effect of Weathering on Material Properties, Testing Methods of Weathered Specimen, Effect of Additives on Weathering, Weathering of Compounded Products, Stabilization and Stabilizers, Biodegradation, Recycling, Environmental Stress Cracking, Interrelation Between Corrosion and Weathering
