Application

Poly(methyl methacrylate-co-ethyl acrylate) (PMMAEA) copolymers may be used to prepare single phase mixture with phenolic derivative. PMMAEA may be used to form latex interpenetrating polymer networks (LIPNs). Membranes of PMMAEA were reportedly used for separation of heavy metal ions from aqueous solutions.

Some acidic nonsteroidal anti-inflammatory drugs (NSAIDs) are poorly soluble in the stomach. In this study, M-5011, d-2-[4-(3-methyl-2-thienyl) phenyl] propionic acid, was used as a model substance. To increase the dissolution rate of M-5011, a solid dispersion of M-5011 was prepared

Dynamic Mechanical Thermal Analysis of cast and sprayed films of an aqueous dispersion of polymethyl methacrylate (Eudragit NE30D) and mixtures with an aqueous dispersion of ethylcellulose (Aquacoat ECD-30) has been undertaken. Such analysis allows the identification of glass transition temperatures
