General description

Ethyl methacrylate (EMA) is a monomer commonly used in the field of polymer industries. It is an ester of methacrylic acid and ethanol and is a colorless liquid with a characteristic odor. EMA is widely used in the production of various polymers such as poly(methyl methacrylate) (PMMA), poly(ethyl acrylate) (PEA), and ethylene-EMA (EE). These polymers find their application in various fields, including medical implant devices, packaging, paper coatings, textile coatings, emulsion polymers, and plastics.

Ethyl methacrylate is a readily polymerizable monomer used for certain types of acrylic resins. The monomethyl ether hydroxyl quinone present in it is an inhibitor that prevents polymerization.

Application

Ethyl methacrylate (EMA) can be used as a monomer in the following applications:
  • To synthesize artificial nanosized latexes of poly(styrene-co-methyl methacrylate) or poly(styrene-co-ethyl methacrylate), which are in producing drug-releasing films.
  • In the production of additive-manufactured methacrylate-based resins used in dentistry.
  • In the synthesis of a star-shaped block copolymer electrolyte for all-solid-state lithium batteries.
  • In the synthesis of a copolymer used as a matrix for semiconductor nanoparticles, which is crucial for the formation of a stable matrix for the quantum dots-copolymer composite material used in optoelectronic applications.
It can also be used to prepare copolymers of EMA on waxy maize starch and hydroxypropyl starch, the potential application of these copolymers are as excipients for compressed non-disintegrating matrix tablets. It may be used to study reactions of n-butyl acrylate and EMA with ozone in the gas phase.
