Study on Weathering Quality of PP/PP-g-AN Blend

Acrylonitrile grafted polypropylene for grafting modification of polypropylene. Different mass polypropylene-g-acrylonitrile (PP-g-AN) was blended with polypropylene. The aging behavior pattern of PP/PP-g-AN was studied on the condition high temperature and illumination. Mechanical properties of different blend ratios were systemic studied on different accelerated weathering process. The results indicated that acrylonitrile grafted polypropylene effective improved weathering resistant of polypropylene.
