    摘要: Disclosed are asphalt modifier compositions containing block copolymers prepared by a block copolymerization of vinyl aromatic hydrocarbons and conjugated diene-based compounds, and specific function additives. The asphalt modifier compositions according to the present invention rarely lower the softening point of asphalt and are dissolved into asphalt at high speeds to form uniform asphalt compositions and to improve the productivity of asphalt compositions.

    摘要: The present invention relates to a catalyst for preparing vinyl aromatic polymer and styrene polymerization using the same, and particularly to a transition metal half metallocene catalyst with a novel structure for preparing syndiotactic styrene polymer having high activity, superior stereoregularity, high melting point and various molecular weight distributions and a process for preparing styrene polymer using the same. The present invention provides a multinuclear half metallocene compound in which two or more of transition metals of groups 3 to 10 on periodic table are connected through bridge ligand simultaneously containing ¥đ-ligand cycloalkandienyl group and ¥ò-ligand functional group and its preparation, and a process for preparing styrene polymer using the compound as a catalyst. Polymers with various molecular weight distributions as well as vinyl aromatic polymer having predominant syndiotactic structure can be prepared with high activity using the multinuclear half metallocene catalyst.
