Preparation and characterization of nano-scaled composites of elastomeric ter-polypropylene blended with iPP through in-situ polymerization strategy

The preparation method of nano-scaled polymeric materials was described in this work. Nano-scaled novel composites of elastomeric ter-polypropylene blended with isotactic polypropylene (iPP) were investigated. The composites were synthesized by zirconium complex/methylaluminoxane(MAO) catalyst system through in-situ polymerization. This novel materials consisted of different lengths of crystallizable iPP segments and rubbery amorphous blocks that polymerized by 1-octene, propylene and ethylene in varying proportions. The mechanical properties of the composites were desired that the iPP segments contributed to the strength and the rubbery amorphous blocks contributed to the flexibility. The result showed that the composites can be used as a kind of elastomer.
