preparation example Construction

[0023] The embodiment of the present invention provides a kind of preparation method of oil-soluble polymer surfactant, and described method comprises the following steps:

[0024] S101: Stir 200 parts by weight of an organic hydrocarbon solvent and 0.01-0.1 parts by weight of an oil-soluble initiator evenly under air-isolated conditions, and then heat to 70-80°C to obtain a mixture A;

[0025] S102: Mix 1000 parts by weight of organic hydrocarbon solvent, 500-800 parts by weight of substance A, 500-800 parts by weight of substance B, and 50-80 parts by weight of substance C at 20-25°C, and then add 10 -20 parts by weight of the oil-soluble initiator, until completely dissolved, to obtain mixture B;

[0026] S103: adding the mixture B to the mixture A dropwise under the condition of cutting off the air, the dropping time is 6-8 hours, and keeping it warm for 1-2 hours after the dropping is completed, to obtain an oil-soluble polymer surfactant;

[0027] Wherein, the substance...

Embodiment 1

[0036] The present embodiment provides a kind of preparation method of oil-soluble polymer surfactant, described method is carried out according to the following steps:

[0037] S101: Add 2kg of gasoline and 0.1g of azobisisobutyronitrile into the reaction kettle, turn on the stirring device in the reaction kettle under the protection of nitrogen to stir evenly, and then heat to 70°C by using a water bath heating method to obtain a mixture A;

Abstract

The invention provides an oil-soluble high molecular surfactant and a preparation method thereof. The preparation method comprises the following three steps: firstly, preparing a mixture A, preparing a mixture B, and dropping the mixture into the mixture A droplet by droplet, so as to obtain the oil-soluble high molecular surfactant. The oil-soluble high molecular surfactant prepared by using the method provided by the invention can be used as a stabilizer of a reversed phase suspension polymerization process, and has the advantages of being good in stability, good in high temperature resistance, acid-alkali resistance and uniform and stable in particle size of formed granular products.

Description

technical field [0001] The invention relates to the technical field of chemical additives, in particular to an oil-soluble polymer surfactant and a preparation method thereof. Background technique [0002] At present, there are few lipophilic polymer surfactants on the market, especially for inverse suspension polymerization. The effect is very poor or even has no effect; the mature oil-soluble polymer surfactant technology of foreign companies and colleges is top secret, and there are few reports in the literature. Contents of the invention [0003] The invention aims at the deficiencies of the prior art, and provides a preparation method of an oil-soluble high molecular surfactant used for reverse-phase suspension polymerization, so that the product of reverse-phase suspension polymerization has good stability. [0004] The present invention is achieved through the following technical solutions, providing a preparation method of an oil-soluble polymer surfactant, said m...
