Methacrylic acid copolymer solubility
WebMethacrylic acid should be stored at temperatures below 15 degrees C. Sources of ignition such as smoking and open flames are prohibited where Methacrylic acid is handled, … WebPolymerization of the methacrylic acid can therefore take place in both the water phase and the suspended organic phase. Since styrene is essentially water insoluble, the methacrylic acid/styrene ratio in the final copolymer product obtained may be significantly less than the ratio of monomers charged.
