A solid catalyst for Polypropylene polymerization and a method for low Volatile organic compound |
| abstract |
The present invention is a propylene polymerization for reducing VOC, characterized in that it comprises an organic electron donor consisting of a combination of a first inner electron donor of titanium, magnesium, halogen, and cyclic diester and a second inner electron donor of diether. As a solid catalyst for use and a method for producing polypropylene using the same, the hydrogen reactivity of the catalyst is improved compared to a conventional method, and the above catalyst has an effect of producing eco-friendly polypropylene with a significantly lower content of volatile organic compounds. |
