Example Embodiment
[0136] Example 1
[0137] A) Prepare the lower HIPE emulsion
[0138] Calcium chloride (60.0 g) was dissolved in 1000 ml of deionized water, and the aqueous phase was maintained at 70 ° C; octyl acrylate (13.5 g), styrene (6.0 g), ethylene glycol dimethyl Acrylic (5.0 g) with span20 (2 g), SPAN 80 (3.5 g), 1173 (1.9 g), uniform, uniform, uniform, is uniform.
[0139] The resulting oil is placed in a 2 liter-shaped stainless steel strip sandwich, stirring the oil phase using a disperser, the dispersion disc is 8 cm, and the starting oil is stirred with a rotational speed of 300 rpm, at the same time in 10 minutes. All water phases were added, and the aqueous phase was added during the dispersing tank in the dispersed tank at 70 ° C. As the aqueous phase added the stirring speed gradually increased, the rotation speed was added to around 1000-1500 rpm, and there was a stable Hierarchical high inner phase emulsion.

[0147] Example 2
[0148] A) Prepare the lower HIPE emulsion
[0149] Calcium chloride (40.0 g), photoinitiator 2959 (purchasing Baili, 0.1 gram) was dissolved in 600 ml of deionized water, and the aqueous phase was maintained at 70 ° C; aloperate (20.0 g) of mixed acrylate (20.0 g), Diethylbenzene (55%, 5.0 g) was uniform and dispersed with CTHROL DPHS (PEG-30 di polyhydroxy stearate, purchasing CRODA, 5.0 g).
[0150] The resulting oil is placed in a 2-liter-shaped stainless steel strip sandwich, and the oil phase is stirred, the dispersion is 8 cm, the dispersion disc is 8 cm, and the drum is stirred with a rotational speed of 200 rpm, at the same time in 10 minutes. All water phase is added, and the aqueous phase is added during the dispersing tank in the dispersed tank at 65 ° C. As the water phase is added, the speed is gradually increased, and the rotation speed is added to around 800-1200 rpm, and there is no stable Hierarchical high inner phase emulsion.

[0158] Example 3
[0159] A) Prepare the lower HIPE emulsion
[0160] Calcium chloride (10.0 g) was dissolved in 500 ml of deionized water, and the aqueous phase was maintained at 80 ° C; oxand ester (25.0 g), trimethylolpropane trimethyl methacrylate (2.0 grams) ) Equal oil phase is made with double glycerol fatty acid ester (purchased in Mike, 3.0 g).
[0161] The resulting oil is placed in a 2-liter-shaped stainless steel strip sandwich, and the oil phase is stirred, the dispersion is 8 cm, the dispersion disc is 8 cm, and the drum is stirred with a rotational speed of 200 rpm, at the same time in 10 minutes. All water phases were added, and the aqueous phase was added during the dispersing tank at 80 ° C. As the addition of the aqueous phase gradually increased, the rotation speed was added at 1000-2000 rp / min, and the formation of stable Hierarchical high inner phase emulsion.
