Methacrylic Acid Glacial (MAA)

Methacrylic Acid Glacial (MAA) is a functional monomer, an unsaturated monocarboxylic acid. The monomer reacts as a vinyl compound and as a carboxylic acid. It easily undergoes polymerization and addition reactions. The copolymers can be obtained with acrylic and methacrylic esters, acrylonitrile, maleic acid esters, vinyl acetate, vinyl chloride, vinylidene chloride, styrene, butadiene, ethylene, and other monomers.

The introduction of Methacrylic Acid Glacial (MAA) in polymers provides them with: 

  • Adhesive ability
  • Hydrophilic
  • Water solubility
  • Required rheological properties

The areas of applications: 

  • Polymethacrylic Acid (PMAA) and Methacrylic Acid Glacial (MAA) copolymers are used in pulp and paper, paint and varnish, textile, medicine, and oil production as binders, film-forming agents, thickeners, adhesives, drilling reagents, dressing preparations, etc.
  • Methacrylic Acid Glacial (MAA) copolymers are used in the manufacture of ion exchange resins and superabsorbents.
  • Methacrylic Acid Glacial (MAA) is used to synthesize its esters and salts.

Methacrylic acid (MAA) is stored in the manufacturer’s packaging (in stainless steel, glass, aluminum or polyethylene containers) in a dry, cool, ventilated room at a sufficient distance from heat or ignition sources.
Guaranteed shelf life - 1 month in the warm season, 2 months in the cold season. Joint storage with flammable and combustible substances, substances having oxidizing properties is not allowed. During transportation, the temperature of methacrylic acid should be maintained in the range of 15-25°C. Methacrylic acid, packed in barrels, is transported in covered wagons, cars that provide storage conditions along the route. At temperatures above 130°C, transportation of acrylic acid in barrels by open road transport is allowed, provided that the product is protected from exposure to sunlight and precipitation. The packaging of barrels with methacrylic acid is carried out on flat pallets. Means of fastening pallets - steel wire, steel or polymer tape, manufactured according to the normative-technical documentation, approved in the prescribed manner. Barrels should be filled to 0.9 volumes and sealed. Bulk methacrylic acid in railway tanks is transported in accordance with the rules for the transport of goods operating on this type of transport. Methacrylic acid (MAA) poured into tank containers, is transported by rail, road, and sea in accordance with the rules for the transport of goods operating on this type of transport.
