    摘要: The present invention provides 1-alkene-acrylate based copolymer prepared by a method comprising step of a radical polymerization reaction of 1-alkene and acrylate based monomer under presence of a metal oxide or Lewis acid. The 1-alkene-acrylated based copolymer according to the present invention is a random copolymer of 1-alkene and a polar monomer, and an amount of a polar group contained in the copolymer is very high so that the alkene is not crystalline. Accordingly, when the copolymer is processed into a polymer film, a transparency of the polymer is not affected. Due to such a feature, the copolymer can be used for optical products.

    摘要: The present invention relates to a synthesis method of metal cyclopentadienide by direct reaction of dicyclopentadiene with a group 1 metal in the presence of an aprotic solvent. Unlike the conventional method depending on retro Diels-Alder reaction of dicyclopentadiene to generate indirectly cyclopentadiene, the method of the present invention favors generation of cyclopentadiene and metal cyclopentadienide as well by adding dicyclopentadiene directly when the reaction temperature reaches to the boiling point of a reaction solvent.
