The low cost and the good performance of poly(vinyl chloride) products have increased the utilization of this polymer in building, mainly in exterior application, such as window profiles, cladding structure and siding. However, ultimate user acceptance of the PVC products for outdoor building applications will depend on their ability to resist photo degradation over long periods of sunlight exposure. To ensure weather ability, the PVC resin needs to be compounded and processed properly, using suitable additives, leading to a complex material whose behavior and properties are quite different from the PVC resin by itself. On the other hand, it is important to perform reliable accelerated weathering test methods. In this regard, factors that influence the degradation of PVC based materials in the service condition, like light and temperature are accelerated. As part of our on-going Patient in the photo stabilization of poly (vinyl chloride), the photo stabilization of PVC was studied using Shiff base Compounds.
