SOLID CATALYST FOR PROPYLENE POLYMERIZATION AND A METHOD FOR PREPARATION OF POLYPROPYLENE USING THE SAME |
摘要 |
Provided are a solid catalyst for propylene polymerization which includes titanium, magnesium, halogen and an internal electron donor mixture of two or more compounds wherein the internal electron donor mixture includes at least one selected from the bicycloalkanes or bicycloalkenes and at least one selected from diethers and succinates, and a method for preparing propylene using the same. As disclosed, it is possible to prepare polypropylene having an excellent stereoregularity with a high production yield. |
