PROPYLENE COPOLYMER FOAMS AND ITS USE. |
| abstract |
A process for forming a polypropylene polymer foam, comprising: (a) in a first stage, polymerizing propylene, (b) in a second stage, copolymerizing propylene and a comonomer in the presence of the product of the first stage, (c) recovering the crystalline propylene polymer product comprising from 0.05 to 15 percent by weight of comonomer based on the total weight of the crystalline propylene polymer, in which steps (a) and (b) of the polymerization are brought to carried out in the presence of a metallocene catalyst system comprising two different metallocene catalyst components and (d) contacting the crystalline propylene polymer product with a foaming agent such that the polypropylene polymer foam is formed. |
