| Abstract: | A new kind of powdered rubber, ultra-fine full-vulcanized powdered rubber (UFPR), was invented and used for toughening polypropylene. The UFPR dispersed well in the PP matrix on a nanoscale. Both toughness and stiffness of PP can be improved by toughening with UFPR. DSC data showed that UFPR has some nucleation effect on PP. When PP was toughened with UFPR and EPDM together, the impact strength showed a synergistic toughening effect. |
