preparation example 1
[0067] In a round bottom flask equipped with a condenser, sodium acrylate and distilled water were placed at a weight ratio of 1:2 under a nitrogen atmosphere, followed by stirring while heating to 60°C. After the stirring was completed, 0.1 mole % potassium sulfate was introduced as an initiator into the mixed liquid based on the total moles of sodium acrylate and was sufficiently dissolved. The obtained resultant was slowly dropped into another flask using a dropping funnel. After completion of the dropwise addition, radical polymerization was performed at 60° C. for 24 hours under a nitrogen atmosphere. Thereafter, the reaction product was precipitated in methanol (methanol) several times, followed by filtration to remove solvent residues, unreacted substances and oligomers, thereby obtaining the white color of the acrylic acid compound (SPA-1) represented by Formula 3. powder:
[0068] [Formula 3]
[0069]
[0070] where l=2,000.
preparation example 2
[0072] Into a round bottom flask equipped with a condenser was placed acrylic acid monomer and methyl cellosolve in a weight ratio of 1:2 under nitrogen atmosphere. The acrylic acid monomer comprises 5 equivalent weight (eq) of sodium acrylate, 80 equivalent weight of acrylic acid and 15 equivalent weight of methyl methacrylate. The acrylic monomer and methyl cellosolve were stirred while heating to 60°C. After the stirring was completed, based on the total moles of acrylic acid monomers, 0.1 mole % azoisobutyronitrile (AIBN) as an initiator was introduced into the mixed liquid and fully dissolved. The obtained resultant was slowly dropped into another flask using a dropping funnel. After completion of the dropwise addition, radical polymerization was performed at 60° C. for 24 hours under a nitrogen atmosphere. Thereafter, the reaction product was precipitated several times in ethyl acetate, followed by filtration to remove solvent residues, unreacted substances, and oligom...
preparation example 3
[0077] A white powder of an acrylic compound (SPA-3) was obtained in the same manner as in Preparation Example 2, except that the acrylic monomer contained 5 equivalents of sodium acrylate, 80 equivalents of acrylic acid, and 15 equivalents of benzylmethacrylate, wherein the acrylic compound was composed of Formula 5 expresses:
[0078] [Formula 5]
[0079]
[0080] where x=32, y=522, and z=98.
