Poly(ethyl methacrylate) (PEMA) is ahydrophobic syntheticacrylate polymer. It has properties similar to the more commonPMMA, however it produces less heat during polymerization, has a lowermodulus of elasticity and has an overall softer texture.[7] It may bevulcanized usinglead oxide as a catalyst[8] and it can be softened using ethanol.
It is used as an impression material of ear canals for the fabrication of hearing aids.[9][10] It is also used in dentistry as a chair-sidedenture reline material for partial and complete dentures as well as a tissue conditioner with implant-supported dentures. It is used as a component of fossil coating and preservation[11] and for fabricating artificial nails[12]
