Poly(methyl methacrylate) - Wikipedia
Poly (methyl methacrylate) (PMMA) is the synthetic polymer derived from methyl methacrylate. It is used as an engineering plastic, and it is a transparent thermoplastic. PMMA is also known as acrylic, acrylic glass, as well as by the trade names and brands Crylux, Hesalite, Plexiglas, Acrylite, Lucite, and Perspex, among several others (see below).
Possibilities of poly(methyl methacrylate) as a passive sampler for ...
2021年7月1日 · Solvent-treated poly (methyl methacrylate) (PMMA) was evaluated as a passive sampler. PMMA–water partition coefficient values were affected by temperature and salinity. Suitable deployment time in seawater was about three weeks for PAHs with logK OW < 5.5. The PMMA predicted the PAH concentrations in mussel within an order of magnitude.
