Abstract
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.
