Embodiment 1
[0018] EXAMPLES Materials used in the present embodiment 500 parts of methacrylic acid, 10 parts silsesquioxane particles, 100 parts of long chain monomer, 100 parts of purified water, 40 parts of acrylic acid sultone, styrene 15 parts , initiator (potassium persulfate + dibenzoyl peroxide, the mixing mass ratio of 2: 1) 1.5 parts, 0.2 parts of a chiral acid, 0.5 parts of a compatibilizing agent.
[0019] Examples of the present embodiment is prepared as follows: acid monomer, purified water, a long-chain monomer is added to the kettle and heated to 50 ℃, when the temperature reaches the open stirring, stirring rate was set to 25 rpm, 35min after holding added silsesquioxane, initiator and molecular weight control agent to maintain the temperature was raised to 80 deg.] C for 3h after stirring for 15min the chiral acid was added dropwise at 90 deg.] C for 1h discharge. The product in toluene was added 2% As and dried under vacuum on a rotary evaporator at a temperature of 80 ℃, dr...
Embodiment 2
[0024] EXAMPLES Materials used in the components and weight ratio of the present embodiment: methacrylic acid, acrylic acid + 480 parts, 15 parts silsesquioxane particles, 80 parts of long-chain monomers, 90 parts of purified water, sodium methacrylate 20 parts of initiator (potassium persulfate + dibenzoyl peroxide, the mixing mass ratio of 3: 1) 1 part, 0.15 parts of a chiral acid, 0.3 parts of a compatibilizing agent; and special synthetic process for the preparation and use of the milling process provided a powder made of dispersant, which is characterized by a uniform spherical powder morphology is simple and easy to use, and 24 months will not fail in a room temperature environment, inorganic materials for general good dispersion, anti-interference ability powerful.
[0025] Examples of the present embodiment is prepared as follows: After the acid monomer, purified water, a long-chain monomer is added to the kettle and heated to 50 ℃, when the temperature reaches the open st...
Embodiment 3
[0030] In this embodiment, the raw material of each component and the weight ratio of: 420 parts of acrylic + maleic anhydride, 12 parts silsesquioxane particles, 50 parts of long-chain monomers, 80 parts of purified water, sodium methacrylate + 2-acrylamido-2-methylpropanesulfonic acid 26 parts of an initiator (potassium persulfate + azobisisobutyronitrile, the mixing mass ratio of 3.5: 1) 0.8 parts, 0.1 parts of a chiral acid, compatibilizer 0.15 parts; and the synthetic procedure using a special process for milling and dispersing agent prepared by the powder, which is characterized by a uniform spherical powder morphology is simple and easy to use, and stored for 24 months in a room temperature environment without failure, for inorganic materials generally have a good dispersing effect, anti-interference ability.
[0031] Examples of the present embodiment is prepared as follows: acid monomer, purified water, a long-chain monomer is added to the kettle and heated to 50 ℃, when ...
