Ultrasound-assisted polymerization of P(AM-DMDAAC
PDA was synthesized by ultrasound assisted aqueous solution polymerization of AM and DMDAAC. The proposed reaction routes for PDA are shown in Scheme 1.A predetermined mass of AM, DMDAAC and other kinds of reagents such as sodium benzoate, EDTA and urea were added into a 250 mL glass vessel with a seal cover.
Synthesis and characterization of bioreducible cationic biarm polymer for efficient gene delivery. cytotoxicity as well. To overcome these problems, new architectures including dendrimer and star-shaped ones, Seoul, South Korea). The results were presented as the mean and standard deviation obtained from three samples.
Synthesis and Properties of Cationic Oligomeric
Three series of new oligomeric cationic surfactants were synthesized. These amphiphiles are trimeric and tetrameric oligomeric quaternary ammonium chlorides, with spacer groups of different lengths separating the individual surfactant fragments. The properties of the compounds, such as Krafft temperatures, surface activity, micellization, viscosifying effects, foaming and solubilizing capacity
Branched cationic polyacrylamide (BCPAM) was synthesized via free-radical solution polymerization of acrylamide (AM) and diallyl dimethyl ammonium chloride (DADMAC) by using pentaerythritol (PETL

- What is poly Aluminium chloride (PAC)?
- In the vast field of water treatment, the role of chemicals in ensuring the purity and safety of water cannot be overstated. Among these, poly aluminium chloride (PAC) has emerged as a cornerstone in both potable water and wastewater treatment processes.
- What is poly Aluminium chloride?
- This article delves into the chemical properties, uses, and safety considerations of poly aluminium chloride, while also examining its pivotal role in the water treatment industry. Poly aluminium chloride, commonly abbreviated as PAC, is a complex chemical compound used primarily as a coagulant in water purification.
- Can PAC be prepared from aluminum chloride solution?
- PAC can be prepared from aluminum chloride solution with the titration of various basification agents such as calcium oxide [ 16, 21 ], sodium hydroxide [ , , ] and sodium aluminate [ 25 ].
- Why is poly Aluminium chloride used in water treatment?
- The primary use of poly aluminium chloride in the water treatment process is to remove impurities and clarify water. This is achieved through a process known as coagulation, where PAC helps to bind particles into larger aggregates that can be easily removed.
