The recent development of weatherability of polypropylene ( PP) materials was reviewed.The factors affecting weatherability of PP were discussed ,including main chain structure ,residual catalyst and external environ-ment.The aging mechanisms of PP such as thermal-oxidative aging and photooxidation aging were analyzed in de-tail.The two aging mechanisms were related to free radical chain reaction.And,this paper generalizes improving weatherability of PP by means of adding organic assistant , adding inorganic nano-materials and selecting suitable processing method.
