摘要： The present invention relates to a method for preparing a styrenic olefin. The method of the present invention comprises the steps of: adding a catalyst and a solvent in a reactor and heating the reactor to create a reflux state; adding an alcohol starting material to the reactor dropwise at a constant rate; removing water generated by adding the alcohol starting material from the reactor, and purifying the obtained styrenic olefin. The method of the present invention is advantageous in minimizing byproducts and preparing styrenic olefins having a variety of substituents in high yield.

摘要： The present invention relates to a transition metal half metallocene catalyst with a noble structure for preparing syndiotatic styrene polymer having high activity, superior stereoregularity, high melting point and broad molecular weight distribution and a process for preparing styrene polymer using the same. The present invention provides a half metallocene catalyst having a single nucleus structure, in which a transition metal in Groups 3 to 10 on the periodic table is connected to a cycloalkanedienyl group or its derivative forming 5-coordinate bond on a side thereof and to any one of triethanolamine, N-alkyldiethanolamine and N-dialkylethanolamine group, all of which have a plurality of binding sites and high steric hinderance, on the other side thereof. The noble metallocene catalyst according to the present invention is useful for preparing highly syndiotatic vinyl aromatic polymer with broad molecular weight distribution and high activity.
