摘要： The present invention provides method of preparing alkene-acrylate-norbornene terpolymer by polymerization of a monomer mixture consisting of alkene, acrylate and norbornene by a radical initiator under the presence of a Lewis acid. In the method of preparing the alkene-acrylate-norbornene terpolymer of the present invention, the terpolymer may be prepared in the mild condition of low temperature and low pressure by using the Lewis acid so that the process is simple and the property of the terpolymer may be easily controlled. In addition, the terpolymer prepared by the method includes the ethylene and the norbornene simultaneously so that it has high glass transition temperature, and the brittle property in forming of film is improved.

摘要： The present invention provides a method for preparation of an 1-alkene-acrylate based copolymer comprising a step of a radical polymerization reaction of 1-alkene and acrylate based monomer under presence of a metal oxide or Lewis acid, and a method for preparation of an alkene-acrylate based copolymer comprising reacting alkene with an acrylate based monomer under presence of a metal oxide. In the method of preparation according to the present invention, the process is simple and properties of the copolymer can be easily controlled by preparing the copolymer in a mild condition of 100°C or less and 200bar or less. In addition, the amount of the polar group of the copolymer prepared by the method is so high that the copolymer can be used for transparent optical products. Since the alkene-acrylate based copolymer prepared by the method is a random copolymer of ethylene and a polar monomer and the amount of the polar group of the polar monomer so high that the crystallinity of the ethylene monomer does not remain in the copolymer, the ethylene- acrylate based copolymer is not affected from a tra nsparency of the polymer and thus may be used for optical products.
摘要翻译：本发明提供一种制备1-烯烃 - 丙烯酸酯基共聚物的方法，其包括在金属氧化物或路易斯酸存在下，1-烯烃和丙烯酸酯类单体的自由基聚合反应的步骤，以及制备烯烃 - 丙烯酸酯基共聚物，其包含在金属氧化物的存在下使烯烃与丙烯酸酯基单体反应。在根据本发明的制备方法中，该方法简单，并且通过在100℃以下且200巴以下的温和条件下制备共聚物可以容易地控制共聚物的性质。此外，通过该方法制备的共聚物的极性基团的量非常高，使得该共聚物可用于透明光学产品。由于通过该方法制备的基于烯烃 - 丙烯酸酯的共聚物是乙烯和极性单体的无规共聚物和极性单体的极性基团的量如此高以至于乙烯单体的结晶度不会残留在共聚物中，所以乙烯丙烯酸酯基共聚物不受聚合物的透明度的影响，因此可用于光学产品。
