Research Progress of Physically Toughened Polypropylene
Polypropylene(PP)is a thermoplastic material,because of its good chemical stability,excellent mechanical properties,non-toxic,lightweight and easy to process and other advantages,is widely used in building materials,auto-motive,aerospace,biomedicine and other fields.However,due to the poor toughness of pure PP,its development and application are very limited,so researchers have been exploring the toughening and modification methods of PP.This pa-per mainly discusses the current research progress of physical toughening modified PP,and prospects the future research direction of toughening modified PP.
