Everything You Need to Know About PolyDADMAC/PDADMAC

by Jordon

PolyDADMAC/PDADMAC is a compound that consists of a large molecule of diallyldimethylammonium chloride because which is also known as a polymer. PDADMAC is widely used in various applications, from dying to water treatment, as the compound is easily dissolved in water, while it’s very easy to dissolve into smaller pieces (monomer), so it doesn’t pose any danger to the environment.

PolyDADMAC Formation

ADMAC the monomer of PDADMAC, is formed in the presence of acid by the reaction of betaine and allyl chloride as this compound is the key and only element of PDADMAC, it is very important to understand their chemistry.

The catalyst in this reaction can be acid H2SO4/HCl, and it is used to quicken chemical reaction. However, Betaine is a natural element/compound present in many plant materials like beet molasses. While the presence of allyl chloride makes the final compound chlorinated, which many people are not aware of (Chlorinated means it will show a salty taste).

DiallyldimethylammoniC8H16ClN) reacts with a tetraamine to form the polymer. The tetraamine used for this reaction is ethylene diamine, which has an -NH2 group on each end of the molecule and two on the central carbon atom. This means that when it reacts with C8H16ClN, it forms 4 covalent bonds with particle of PDADMAC. These several bonds support to create the strong resulting product that is durable and highly effective at binding to and neutralizing negatively charged ions in the solution.

Properties of PolyDADMAC/PDADMAC

PolyDADMAC has been used in many applications, unlike any other chemicals of the same class. It is because this compound is safer to use not only for human health but also for the environment. So, below we will briefly discuss the physical and chemical properties of this compound that make it worth using in your industry;

Tasteless and Odorless

One of the major applications of polydadmac is wastewater management (WWM). The management of wastewater is always a greater concern of healthcare and environmental safety departments as it damages both.

However, not any chemical can use in the processing and cleaning of this water as this water is later used for human consumption. The tasteless and odorless nature of PolyDADMAC makes it an ideal chemical to clean the water as it leaves no impact of its presence after cleaning.


The PolyDADMAC is known for its water solubility, which makes it easier to use it in water treatment without combining it with other chemicals. This property also allows the use of this compound in the coloring of furniture and textile products, where it is used as a fixing agent and provides long-lasting color.

High pH Range

The PolyDADMAC is adjustable to work on a large pH range which extends its usage line. You can use this chemical at a pH of 0.5-1.4 (acidic).

Flocculating Agent

PDADMAC is used as a flocculating agent to treat the water. The flocculating agent is a chemical that floc all the waste material in the water together. This property makes it easier to remove such elements from water as they precipitate at the bottom of the water in large junk pieces. While the good thing is you only have to use a small amount of PDADMAC to get amazing a result which is a huge benefit compared with inorganic flocculating.


The PDADMAC is an important chemical with wide applications. However, the major focus is always water treatment. It is because, unlike other uses, water is the only thing that we consume. So, when using this compound in the water, you should clearly understand the qualities and amount being used. In this article, we have explained all the basic information about this compound that will assist you in its usage.
