Increasing the resistance to degradation of polymeric materials under the influence of atmospheric influences or improving the resistance to degradation of polymeric materials under the influence of atmospheric influences

摘要

A polymeric material containing a halogen-containing polymer such as PVC, an inorganic hydroxide and, an acrylic material is described. The presence of the inorganic hydroxide provides a material of superior weathering resistance as compared to materials comprising halogen-containing polymers which do not contain hydroxide.
