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

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 - 12 months. 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.
