WebElvacite® Methyl Methacrylate Resins are polymers based on poly methyl methacrylate (PMMA). They are available as free flowing, spherical beads that are easily dissolved in strong solvents. The glass transition temperature (Tg) is higher and their solubility is lower than other Elvacite®. Because of these properties they yield films with much ... WebMMA is a raw material for the manufacture of other methacrylates. These derivatives include ethyl methacrylate (EMA), butyl methacrylate (BMA) and 2-ethyl hexyl …
WebPoly(ethyl methacrylate) materials are very similar to PMMA-based products, but with a lower T g (Fig. 3§4.5) and so have a lower modulus of elasticity. At the same time, the additional free volume means greater water sorption and, reportedly, more discolouration (although this may have more to do with the use of amine initiators; cf. §1.1 , 5§3 ). WebDec 5, 2013 · Poly (methacrylic acid-co-ethyl acrylate) 1:1 is a relatively soft polymer requiring the 10–20% addition of plasticizer to achieve good film formation at low coating temperatures of 25–30 °C. Suitable plasticizers are triethyl citrate, dibutyl sebacate, polyethylene glycol and propylene glycol.
