thermofusion dyeing levelling agent PA - Preparation method
Open Data Verified Data
Add 40kg of acrylamide, 6kg of polymerizer, and 400kg of deionized water to the reactor at room temperature, stir and dissolve. Then add 160kg of acrylic acid, stir for 0.5h, and start adding ammonium persulfate aqueous solution (equivalent to 0.3% of monomer volume) dropwise. After dripping, add a small amount of sodium bisulfite. React for 5-6 hours under continuous stirring. When the material is discharged, the finished product is obtained.

thermofusion dyeing levelling agent PA - Introduction
Acrylamide is a colorless crystalline solid with the chemical formula C3H5NO. It has high solubility and reactivity, widely used in chemistry, environment, biology, medicine and other fields.
Acrylic copolymer is a polymer formed by co-polymerization of acrylamide and acrylic acid. According to different proportions and conditions, acrylic copolymers with different properties can be obtained. In general, acrylic copolymers have the following properties:
1. Good water absorption: acrylic acid copolymer can absorb a large number of water molecules to form a hydrogel state, which is widely used in moisturizing, hydrogel materials and other fields.
2. Polymer chain flexibility: acrylic copolymer polymer chain structure makes it soft, can be used in coatings, adhesives, plastic modification and other fields.
3. Excellent Ion Exchange Performance: acrylic acid copolymer with ionized groups, can be used for water treatment, ion exchange resin and other related applications.
4. Biocompatibility: Acrylic acid copolymer has good biocompatibility under certain conditions, and can be used for drug release and artificial organs in the medical field.
The process for producing a copolymer of acrylamide and acrylic acid is generally carried out by radical polymerization. The specific method can be solution polymerization, emulsion polymerization, suspension polymerization and other ways.
Regarding the safety information of acrylamide and acrylic acid copolymers, acrylamide may be carcinogenic to humans in pure form, and irritating to skin and eyes. Therefore, it is necessary to wear appropriate protective equipment during use and ensure its correct use and storage. At the same time, acrylic copolymer products need to comply with relevant safety operating procedures during use, and ensure proper ventilation and protection measures to prevent adverse effects from causing damage to the human body and the environment.
