Application | Polydimethyldiallylammonium chloride is a linear polymer with cationic groups. Therefore, it presents physical and chemical functions such as adsorption, charge neutralization and ion exchange that neutral polymers do not have. Cationic polymers have relatively fixed positive charges, and have strong binding force on negatively charged fibers, plastics and other surfaces. They are widely used as antistatic agents, spinning oils, and flocculants for synthetic materials. Polydimethyldiallylammonium chloride polymer antistatic agent with high molecular weight, rapid dissolution, less monomer residue and excellent antistatic performance was synthesized by aqueous solution polymerization. Polydimethyldiallylammonium chloride is a kind of aldehyde-free and pollution-free fixing agent, which can be used in the fixing treatment of fabrics. However, the reaction time and temperature and the pH value of the fixing bath should be controlled in the fixing process, so as to ensure the best state of color fastness and improve the dyeing effect and fixing effect. |
preparation | the polymerization method of dimethyldiallylammonium chloride (DDAC) aqueous solution was studied. the effects of monomer concentration, sodium ethylenediaminetetraacetate (EDTA) concentration, initiator type and dosage on polymer intrinsic viscosity were analyzed and discussed. the application of polydimethyldiallylammonium chloride (PDDAC) polymer antistatic agent on polypropylene fiber was introduced. The 70% dimethyldiallylammonium chloride monomer aqueous solution was heated to 80 ℃, the pH value was adjusted to 4~6, oxygen was removed with nitrogen for 1 hour, an initiator was added, and polymerized at 80 ℃ for 4 hours to prepare polydimethyldiallylammonium chloride. The main raw materials are DDAC (laboratory synthesis), initiator azobisisoheptonitrile (ABVN), diisopropyl bicarbonate (IPP), ammonium persulfate (APS), etc., all of which are chemically pure reagents. Experimental principle DDAC is a water-soluble monomer, so it can be polymerized in aqueous solution in the presence of an initiator. The polymerization reaction equation is shown in the following figure: Figure 1 Preparation of Polymerization Reaction Equation Polymerization Method A stirrer, thermometer, air duct and condenser are installed in a 500ml four-mouth bottle and placed in a super constant temperature water bath. Add the 70% DDAC aqueous solution to a three-mouth bottle, adjust the pH value to 4~6, heat the monomer aqueous solution to 80 ℃, remove oxygen with nitrogen for 1 hour, add an initiator, polymerize at 80 ℃ for 4 hours, and then dilute to 40% discharge. |
use | this product has been widely used as a polymer flocculant in tap water and sewage treatment. Especially for the high turbidity raw water in the river flood season, in order to effectively coagulate the clay, silica, microorganisms and hydrated metal oxides in the raw water, this product is usually used to treat flocculant, dehydrating coagulant |
