Problems solved by technology

That is, since the content of the polar monomer is not high, the crystallinity of polyethylene exists in the copolymer, so there is a limitation in using the copolymer for optical materials such as transparent films, etc.

Embodiment 1

[0091] After the 125mL high-pressure reactor was evacuated, it was filled with argon. Under an argon atmosphere, a metal nanocatalyst (2.86 g, 28.05 mmol) containing 0.1 wt% ruthenium, 23 mL of toluene, and methyl methacrylate (2.81 g, 28.05 mmol) were added to the reactor. Separately, 0.056 mmol of initiator AIBN dissolved in toluene was added. Then, after charging ethylene at a pressure of 30 bar, the temperature of the reactor was raised to 70° C., stirred at a rate of 500 rpm with a magnetic bar, and polymerized for 18 hours to prepare a polymer solution.

[0092] After the polymerization reaction is completed, the reaction temperature is lowered to normal temperature, and the metal nano-catalyst is recovered by filtration. Subsequently, ethanol not used as a solvent was added dropwise to the polymer solution from which the metal nanocatalyst was removed to precipitate the polymer in a solid form. The supernatant was removed by precipitating the solid phase, ethanol was ...

Embodiment 2

[0094] Except for using a metal nanocatalyst containing 1 wt% ruthenium, the same polymerization conditions and post-treatment process as in Example 1 were used to prepare a copolymer.

Embodiment 3

[0096] Except for using a metal nanocatalyst containing 5 wt% ruthenium, the same polymerization conditions and post-treatment process as in Example 1 were used to prepare a copolymer.

Abstract

The present invention relates to a catalytic composition for producing a 1 -alkene-acrylate copolymer that includes a metal nano catalyst, and a method for producing a 1-alkene-acrylate copolymer. In the catalytic composition for producing a 1 -alkene-acrylate copolymer, since the content of the polar comonomer is high, it may be used to produce the 1-alkene-acrylate copolymer that has no crystallinity and is capable of being used as an optical material. The method for producing the 1-alkene-acrylate copolymer may be produced by using a simple process of a mild polymerization condition without a polymerization condition of high temperature and high pressure, and it is easy to control physical properties.

Description

technical field [0001] The present invention relates to a catalytic composition for preparing 1-alkene-acrylate copolymer and a method for preparing 1-alkene-acrylate copolymer comprising a metal nano catalyst. This application claims priority from Korean Patent Application No. 10-2007-0122198 filed with KIPO on November 28, 2007, the disclosure of which is incorporated herein by reference in its entirety. Background technique [0002] When 1-alkenes, specifically ethylene, are copolymerized with alkyl acrylate comonomers, polymers can be formed with different physical properties not obtainable in pure polyethylene. Examples of physical properties include adhesion strength and low temperature toughness, etc., and these physical properties are greatly improved with an increase in the content of the alkyl acrylate comonomer. Therefore, the development of copolymers comprising intermixed 1-alkenes and another comonomer has attracted much attention. [0003] In the usual prior...
