Chemical Structure: Acrylic Homopolymer is a high-molecular polymer
formed by the polymerization of acrylic acid monomers. The molecular
chain is mainly composed of repeating acrylic acid units, with a general
structural formula of [-CH₂-CH(COOH)-]ₙ, where n represents the degree of polymerization, determining the molecular weight and properties of the polymer.
Physical Properties: Typically a colorless to light
yellow transparent liquid, and some appear as white powder or granular.
It has good solubility, dissolving in water to form a uniform solution,
and can also dissolve in polar organic solvents such as ethanol and
acetone. Additionally, its viscosity increases with the increase of
molecular weight and concentration.
Chemical Properties: The molecular chain contains
carboxyl groups (-COOH), giving it certain acidity, which can undergo
neutralization reaction with alkalis to form corresponding salts.
Meanwhile, carboxyl groups can participate in chemical reactions such as
esterification and amidation, modifying the polymer or crosslinking
with other substances to improve performance and meet different
application requirements. It also has good thermal stability and
oxidation resistance, maintaining structural and performance stability
within a certain temperature range and oxidative environment.
Application Fields
Water Treatment: As a scale inhibitor and
dispersant, it can inhibit the crystallization and precipitation of
insoluble salts such as calcium carbonate, calcium sulfate, and barium
sulfate, preventing scale formation on pipes and equipment surfaces. It
is widely used in industrial circulating cooling water systems, boiler
water systems, reverse osmosis water treatment systems, etc., to improve
heat transfer efficiency and service life of equipment.
Textile and Dyeing Industry: Used as a textile
sizing agent to enhance the adhesion of sizing to fibers, making yarn
smoother during weaving and reducing breakage; as a dyeing auxiliary to
improve the dispersibility and permeability of dyes, enhancing dyeing
uniformity and color fastness, and also playing a role in anti-staining
and color fixing.
Coatings and Adhesives: Applied in manufacturing
acrylic resin coatings, which feature good weather resistance, water
resistance, chemical corrosion resistance, and decorative properties,
widely used in architectural coatings, automotive coatings, wood
coatings, etc. In adhesives, it can improve adhesion strength, water
resistance, and aging resistance for bonding materials like paper, wood,
leather, and plastics.
Paper Industry: As a paper strength enhancer, it
improves the strength and stiffness of paper; as a paper sizing agent,
it enhances water resistance and printing adaptability; and as a pigment
dispersant, it ensures uniform dispersion of pigments in paper,
improving gloss and whiteness.
Main Manufacturers
Kairui Chemical: Its produced kr-1000 acrylic
homopolymer is a low-molecular-weight polyacrylic acid with a molecular
weight of about 2000, effectively inhibiting the precipitation of
low-solubility salts such as calcium carbonate, calcium oxalate, calcium
sulfate, and barium sulfate. Contact InformationContact Information :
