| Description: |
Methacrylic anhydride, an organic compound derived from methacrylic acid and classified under acrylic acids, is predominantly used as a monomer in polymer production. Notably, it is used to synthesize poly(methacrylic acid) and its copolymers, which are valued for their diverse applications across various industries. These applications include bio-renewable resins, pH-sensitive hydrogels, thermosets, coatings, adhesives, and plastics, owing to their outstanding chemical and thermal stability. During the polymerization process of methacrylic anhydride, Topanol A is the most commonly used inhibitor. Typically added in small amounts (2,000 ppm), Topanol A prevents undesirable side reactions, ensuring controlled and high-quality polymer formation. |
| Application: |
Methacrylic anhydride can be used as a starting material to synthesize:
Methacrylated chondroitin sulfate pH-sensitive hydrogels by copolymerization reaction. These hydrogels can be used in drug delivery systems.
High-performance lignin-based thermosets.
Gel polymer electrolyte, which is then integrated with the cathode to form high-performance lithium-ion batteries.
Methacrylic anhydride can be also used as a precursor to synthesize bio-renewable resins for composite applications. |
