Embodiment 1
[0169] 60 g of stearyl acrylate, LATEMUL PD-420 (manufactured by Kao Corporation, polyoxyalkylene alkenyl ether, HLB=12.6) 2 g, LATEMUL PD-430 (manufactured by Kao Corporation, polyoxyalkylene alkenyl ether) were added to a 500 mL flask. Ether, HLB=14.4) 2g, octadecyldimethylamine hydrochloride 3g, tripropylene glycol 20g, and water 162.75g were mixed and stirred at 45°C to obtain a liquid mixture. The mixture is irradiated with ultrasonic waves to emulsify and disperse all the monomers. Next, 0.25 g of azobis(isobutylamidine) dihydrochloride was added to the mixed liquid, and it was radically polymerized at 60° C. for 6 hours under a nitrogen atmosphere to obtain a non-fluorine-based compound with a polymer concentration of 26% by mass. polymer dispersion.
Embodiment 2
[0171] 55 g of stearyl acrylate, LATEMUL PD-420 (manufactured by Kao Corporation, polyoxyalkylene alkenyl ether, HLB=12.6) 2 g, LATEMUL PD-430 (manufactured by Kao Corporation, polyoxyalkylene alkenyl ether) were added to a 500 mL flask. Ether, HLB=14.4) 2g, 2-hydroxyethyl acrylate 5g, octadecyldimethylamine hydrochloride 3g, dodecyl mercaptan 0.15g, tripropylene glycol 20g and water 162.6g, and at 45 ℃ Mixing and stirring are performed to obtain a liquid mixture. The mixture is irradiated with ultrasonic waves to emulsify and disperse all the monomers. Next, 0.25 g of azobis(isobutylamidine) dihydrochloride was added to the mixed liquid, and it was radically polymerized at 60° C. for 6 hours under a nitrogen atmosphere to obtain a non-fluorine-based compound with a polymer concentration of 26% by mass. polymer dispersion.
Embodiment 3
[0173] 55 g of stearyl methacrylate, 2 g of LATEMUL PD-420 (manufactured by Kao Corporation, polyoxyalkylene alkenyl ether, HLB=12.6), LATEMUL PD-430 (manufactured by Kao Corporation, polyoxyalkylene group) were added to a 500 mL flask. Alkenyl ether, HLB=14.4) 2g, 2-hydroxyethyl acrylate 5g, octadecyldimethylamine hydrochloride 3g, dodecyl mercaptan 0.05g, tripropylene glycol 20g and water 162.7g, and in Mixing and stirring were performed at 45° C. to obtain a mixed liquid. The mixture is irradiated with ultrasonic waves to emulsify and disperse all the monomers. Next, 0.25 g of azobis(isobutylamidine) dihydrochloride was added to the mixed liquid, and it was radically polymerized at 60° C. for 6 hours under a nitrogen atmosphere to obtain a non-fluorine-based compound with a polymer concentration of 26% by mass. polymer dispersion.
