Future Prospects for Accelerated Weathering of Polymeric Materials.

摘要

The degree of correlation obtained between results of natural and artificial weathering for a wide range of polymers is discussed. It is noted that the greatest successes in achieving satisfactory correlation continue to be reported for olefin polymers. However, it is concluded that, whilst artificial weathering may continue to be cautiously employed as a means of screening formulations prior to outside exposure, greater emphasis should be given to applying sensitive methods of evaluating the physical-chemical and mechanical changes occurring in materials exposed naturally outdoors.
