Title: Method for adjusting syndiotactic polyolefin melting point and molecular weight by using metallocene catalyst
Inventor: EWEN JOHN
IPC: C08F4/60
Filed: 2002-07-05
Abstract: PROBLEM TO BE SOLVED: To provide a method for changing syndiotactic polyolefin melting points and molecular weights by using a metallocene catalyst having a substituent at a specified location on the aryl ring of the fluorine ligand. SOLUTION: With an electron donating substituent, such as a dialkyl amino, halogen, or alkoxy group, at C1, C2, C3 or at C2 and C7 on the fluorine, catalytic activity is lowered causing a decrease in polymer molecular weight. To the contrary, with an electron donating substituent, such as an alkyl, dialkylamino, halogen, or alkoxy, at C4, not only catalytic efficiency is enhanced but also a remarkable increase in polymer molecular weight is effected. Presence at C2 and C7 of a bulky hydrocarbyl substituent, such as an alkyl, cycloalkyl, or aryl group, elevates the melting point. Presence at C4/C5 of a bulky hydrocarbyl substituent, such as an alkyl, cycloalkyl, aryl, alkoxy, or dialkyl- amino group, lowers the melting point. Presence of a multiplicity of substituents on the fluorine adds to their effects.
