Polymaleic anhydride

WebMar 18, 2024 · Maleic anhydride (or maleic acid) and acrylic acid (or methacrylic acid) can be homopolymerized to give polymaleic anhydride (or polymaleic acid) and polyacrylic acid (or polymethacrylic acid), respectively, as shown in Fig. 8. WebThe temperature at which the decomposition reaction of maleic anhydride begins is a function of the content of alkali metal pollutants in maleic anhydride. When the content of alkali metal ions reaches 10 ppm, the temperature at which the decomposition reaction of maleic anhydride starts is about 390-400°F (200-204°C).
