Embodiment 1
[0020] Place 52ml of polyamino compound divinyltriamine in a 250ml three-necked flask, cool in an ice-water bath, and place in N 2 Under protection, use a constant pressure funnel to slowly add a mixed solution of 43ml methyl acrylate and 100ml methanol dropwise, and react at room temperature for 4 hours after the dropwise addition to obtain light yellow transparent AB 2 type monomer. Then it was transferred to a rotary evaporator eggplant-shaped flask, methanol was removed under reduced pressure, the temperature was raised to 150°C to continue the reduced-pressure reaction for 4 hours, and the reaction was stopped to obtain a viscous light yellow amino-terminated hyperbranched compound.
[0021] Put 10 g of the above-mentioned amino-terminated hyperbranched compound into a three-necked flask, add a certain amount of water to completely dissolve the amino-terminated hyperbranched compound, stir to dissolve, and then dropwise add 25 g of quaternizing agent glycidyl trimethyl ch...
Embodiment 2
[0023] 52ml of polyamino compound triethylenetetramine is placed in a 250ml three-necked flask, cooled in an ice-water bath, in N 2 Under protection, use a constant pressure funnel to slowly add a mixed solution of 43ml methyl acrylate and 100ml methanol dropwise, and react at room temperature for 4 hours after the dropwise addition to obtain light yellow transparent AB 2 type monomer. Then it was transferred to a rotary evaporator eggplant-shaped flask, methanol was removed under reduced pressure, the temperature was raised to 150°C to continue the reduced-pressure reaction for 4 hours, and the reaction was stopped to obtain a viscous light yellow amino-terminated hyperbranched compound.
[0024] The above-mentioned amino-terminated hyperbranched compound 10g is put into a three-necked flask, a certain amount of water is added, stirred and dissolved, and then added dropwise to a three-necked flask containing 25g of quaternizing reagent 3-chloro-2 hydroxypropyl trimethylammoni...
Embodiment 3
[0026] Place 52ml of polyamino compound divinyltriamine in a 250ml three-necked flask, cool in an ice-water bath, and place in N 2 Under protection, use a constant pressure funnel to slowly add a mixed solution of 43ml methyl acrylate and 100ml methanol dropwise, and react at room temperature for 4 hours after the dropwise addition to obtain light yellow transparent AB 2 type monomer. Then it was transferred to a rotary evaporator eggplant-shaped flask, methanol was removed under reduced pressure, the temperature was raised to 150°C to continue the reduced-pressure reaction for 4 hours, and the reaction was stopped to obtain a viscous light yellow amino-terminated hyperbranched compound.
[0027] 10g of the above-mentioned amino-terminated hyperbranched compound is put into a three-necked flask, a certain amount of water is added, stirred and dissolved, and then an aqueous solution containing 10g of quaternizing agent glycidyltrimethylammonium chloride (GTMAC) is added dropwis...
