Poly(ethyl acrylate)

Poly(ethyl acrylate) is a polymer that is formed by the polymerization of ethyl acrylate monomers. It has a very low glass transition temperature of -24°C, which makes it a sticky polymer at room temperature. Unlike poly(methyl methacrylate), it does not have a pendant methyl group on the carbon atom, and it is more flexible at room temperature due to its lower Tg.From: Synthesis and interfacial properties of a novel inverse demulsifier of nanosized poly[(methyl methacrylate)-co-(ethyl acrylate)-co-(methacrylic acid)-co-(acrylamide)] latex [2018], Seymour/Carraher's Polymer Chemistry [2019]

Processing & Manufacturing Routes: Commercial poly(ethyl acrylate) is usually prepared by free radical soln. and emulsion polymerisation. It is processed by injection moulding, blow moulding, extrusion and thermoforming Applications: Acrylics are widely used in paints, coatings and lacquers, in paper industry, as radiation curable systems, as adhesives and sealing compds., in gaskets for automotive industry and in textile and leather industries

The latex obtained from oil initiators coagulates. There may be several reasons for this phenomenon. Usually, radicals generated by the oil-soluble initiators reacted with the monomers in the oil-soluble monomer droplet to form primary particles by droplet nucleation. The polymerization behavior is similar to suspension polymerization. Most MMA and EA could be polymerized in monomer droplets and the binary copolymer was formed. EA as the principal monomer gives the poly(ethyl acrylate), which has a very low glass transition temperature (−24°C) and thus it is a sticky polymer at room temperature. The copolymer of MMA and EA was anticipated to be a sticky polymer and a relatively unstable latex. Furthermore, radicals generated by the oil-soluble initiators also can react with the monomers in the monomer-swollen micelles to form particles and MAA and AM can be copolymerized. The copolymer of MAA and AM can increase latex viscosity so coagulation occurred.
