Abstract

Abstract: PP-g-AN and TiO2 were introduced into polypropylene in order to improve its aging resistance.The aging of the system was monitored for 500, 1000, 1500, 2000 and 2500h. When the PP-g-AN/TiO2 content was 590/5/5, the tensile strength of modified polypropylene reached a maximum of 25.58MPa and an impact strength of 62.73 KJ/m2 after accelerated aging 2500h.
