| Abstract: | For the purpose of extending the application fields of hard pitch,as a kind of petroleum industry by-product,the highsoftening-point hard pitch was used as a novel polystyrene modification additive.The pitch was filled into polypropylene by melting mix method.The modified polymers were characterized by Furrier infrared spectrum and the mechanical properties of these modified polymers were tested respectively.The result shows that the ultraviolet aging-resistance of polypropylene is improved for the reason of pitch's property of ultraviolet absorption.The mechanism was discussed and the prospect of hard pitch used for a kind of polymer additive was given. |
