WebHerein, we report a new approach for the sulfonation of polyether ether ketone (PEEK) following a shorter path of reaction undertaken at 60 °C under ultrasonication. The application of this method enabled the reduction of the reaction time from several hours to less than one hour, achieving a relevant sulfonation degree. The sulfonated-PEEK (SPEEK) … WebPoly(methyl methacrylate) (PMMA) is the synthetic polymer derived from methyl methacrylate.Being an engineering plastic, it is a transparent thermoplastic.PMMA is also known as acrylic, acrylic glass, as well as by the trade names and brands Crylux, Alfaplas, Plexiglas, Acrylite, Lucite, and Perspex, among several others ().This plastic is often used … WebPolyester Foam vs. Polyether Foam. Traditionally, polyester foam has a higher “tensile” strength than its polyurethane foam counterpart, polyether foam. Polyester foam is also more resistant to hydrocarbons and alcohols than polyether foam.
