THERMOPLASTIC PROPYLENE ELASTOMERS AND ONE POT/TWO CATALYSTS PROCESS TO PRODUCE THEM |
摘要 |
This invention relates to polypropylene blends, particularly blends of high molecular weight amorphous polypropylene with lower molecular weight isotactic polypropylene. These blends exhibit unusual elastomeric properties. This invention also relates to the production of polypropylene blend compositions using at least two catalyst systems, one for producing amorphous polypropylene and one for producing crystalline polypropylene.
