Articles formed from foamable polypropylene polymer |
摘要 |
This invention relates generally to articles formed from polypropylene polymer foams and desirably isotactic polypropylene polymer foams. The polypropylene polymers are obtained from metallocene catalysis. The polypropylene polymer has molecular weight distributions and densities that fall within broad ranges. The polypropylene polymer foam may be prepared in a multiple stage polymerization process using the same metallocene component in at least two stages.
