General description

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) may be used to prepare copolymers of EMA on waxy maize starch and hydroxypropylstarch, 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.
