Methyl methacrylate is an unsaturated ester, abbreviated as MMA in English, is a colorless transparent liquid at room temperature, volatile, easy to explode, easy to burn, and its volatile gas has a pungent odor. Soluble in alcohols, ethers, ketones and chlorinated hydrocarbons, slightly soluble in aliphatic ethers, alcohols, slightly soluble in water, with water, methanol can form azeotropes.
MMA is mainly used in the fields of polymerization and copolymerization, and special polymerization processes are required for each application. The initiators are free (organic peroxides, azo compounds) or ionic.
The plexiglass can be obtained by bulk polymerization, used for artificial decoration materials, architectural industrial parts, optical information materials and electrical component packaging.
Coatings, lacquers, adhesives, water repellents, lubricant additives, etc. can be prepared by emulsion polymerization.
It can replace styrene as a cross-linker, dilute the unsaturated polyester resin, and make natural and synthetic rubber modifiers.
Methyl methacrylate is mostly used in the organic glass industry, but it is also widely used in many other fields. At present, medical functional polymers (polymer materials and macromolecules) and textiles (acrylic second monomers) are used as functional monomers, and are widely used in coatings, paints, PVC processing aids and adhesives. .
