What are the commonly used cationic functional monomers?

Cationic functional monomers are a class of polymer monomers with cationic groups, which are able to introduce positive charges during polymerization, thus giving polymers special physicochemical properties. Cationic functional monomers have a wide range of applications in materials science, biomedicine, environmental protection and other fields. Next, we will introduce several major cationic functional monomers, their functional characteristics and application areas.

Dimethyldiallylammonium chloride

Alias: dimethyldiallylammonium chloride, diallyldimethylammonium chloride, DADMAC, CAS No.: 7398-69-8

Dimethyldiallylammonium chloride is a high purity, polymerization grade, quaternary amine salt, high charge density cationic monomer. Its DMDAAC aqueous solution, the appearance of colorless transparent, non-irritating odor liquid, slightly thick, dimethyldiallyl ammonium chloride is easily soluble in water.

Dimethyldiallylammonium chloride as a cationic monomer through homopolymerization or copolymerization with other monomers to form polymer series products. Its polymers, in textile dyeing and finishing auxiliaries can be used as aldehyde-free color fixing agent, film on the fabric to improve the dyeing fastness; in papermaking auxiliaries can be used as retention filtering agent, paper coating antistatic, AKD ripening accelerator; in the process of water treatment can be used for decolorization, flocculation and purification; in daily-use chemicals can be used in shampoo shampoos combing agent, wetting agent, and antistatic agent; in the oilfield chemicals, can be used for clay In oil field chemicals, it can be used as clay stabilizer and cationic additive of acidification and fracturing fluid. Its main function is electric neutralization, adsorption, flocculation, purification, decolorization, especially as a modifier of synthetic resin, giving conductivity, antistatic.

Diallylamine hydrochloride

Alias: Allylamine Hydrochloride, Diallylamine Chloride, Diallylamine Hydrochloride, N-2-propenyl-2-propen-1-amine hydrochloride, CAS No.: 6147-66-6

Diallylamine Hydrochloride is a high purity, polymerization grade, primary amine salt, high charge density monomer.

It can be mainly used as an intermediate in pharmaceutical manufacturing, and can be homopolymerized or copolymerized with other monomers to form a series of polymer products. Its polymers, in textile dyeing and finishing auxiliaries, can be used as aldehyde-free color fixing agent, film on the fabric to improve dyeing fastness; in papermaking auxiliaries, it can be used as retention filtering agent, paper coating antistatic, AKD maturation promoter; in oilfield chemicals, it can be used as clay stabilizers, cationic additives for acid fracturing fluids, and so on. Its main role is electric neutralization, adsorption, flocculation, purification, decolorization, especially as a modifier of synthetic resin, giving conductivity, antistatic.

Methacryloxyethyl trimethyl ammonium chloride

CAS No.: 5039-78-1, DMC is made from dimethylaminoethyl methacrylate as raw material and chloromethane by quaternary ammonium reaction, mainly used as copolymerization monomer for cationic polymerization, copolymerized with acrylamide to produce cationic polyacrylamide, which can be used in sludge dewatering process of sewage treatment plant and wastewater treatment of papermaking, coal flotation, printing, dyestuff and other industries. In addition, DMC can also be used in the production of paper-making auxiliaries, cosmetics and so on.

Diallylamine

CAS No.: 124-02-7, used in the production of crosslinked aldehyde-free color fixing agent (copolymerization of diallylamine and dimethyldiallylammonium chloride), cross-linking agent, pharmaceutical intermediates, and intermediates for agrochemicals, dyes and coatings, organic synthesis and resin improvers. It can also be used in the preparation of amphoteric polymers and so on.

Summary:

Different cationic functional monomers have different functional characteristics and application areas, including pulp and paper industry, water treatment, textile industry, inks, pharmaceuticals, personal care products and so on. The selection of suitable cationic functional monomers depends on the specific application requirements and desired properties. With the continuous progress of science and technology and the improvement of people's requirements on material properties, the research and application of cationic functional monomers will become more and more extensive, bringing more possibilities and opportunities for the development of human society.
