Chemical Structure and Reactivity

• Key Features: Contains two methacrylate groups (CH2=C(CH3COO-) linked by an ethylene glycol chain, making it a bifunctional monomer.
• Polymerization:
  • Undergoes free-radical polymerization (initiated by heat, light, or initiators like AIBN) to form cross-linked polymers.
  • The double bonds react with other monomers (e.g., methyl methacrylate) to create copolymers with high mechanical strength and chemical resistance.

Applications

1. Polymer Chemistry
   • Crosslinking Agent: Used in synthesizing:
     • Dental resins (e.g., composite fillings) for hardness and durability;
     • Ion-exchange resins for water treatment;
     • Hydrogels for biomedical applications (e.g., drug delivery systems).
   • 3D Printing: As a component in photopolymer resins for stereolithography (SLA) due to its rapid curing property.
2. Material Science
   • Reinforces plastics and coatings, improving resistance to solvents and heat.
   • Used in the production of microbeads for chromatography and cosmetics (e.g., exfoliants).
3. Biomedical Field
   • Prepares porous scaffolds for tissue engineering and controlled-release drug carriers.

Safety and Handling

• Hazards:
  • Irritant to skin, eyes, and respiratory tract; may cause allergic reactions (e.g., dermatitis) upon prolonged exposure.
  • Toxic if ingested; vapor is harmful when inhaled.
  • Flammable; vapor forms explosive mixtures with air.
• Precautions:
  • Use in fume hoods with proper ventilation; wear gloves, goggles, and lab coats.
  • Avoid contact with skin and eyes; rinse immediately with water if exposed.
  • Store in a cool, dry place away from light and heat, with inhibitors (e.g., MEHQ) to prevent polymerization.
• Regulations: Classified as a hazardous substance (e.g., EU CLP: H226, H315, H317, H335).
