General description

Methacryloyl chloride is the clear to slightly colored acid chloride of methacrylic acid. Monomethyl ether hydroquinone is added as a stabilizer to prevent auto polymerization. Reaction with diisopropyl ether in presence of metal salts is rigorous.

Application

Methacryloyl chloride is used in the manufacture of polymers:
  • Monomer 2-methacrylamido-caprolactam was prepared by reacting methacryloyl chloride with racemic a-amino-e-caprolactam.
  • Functional monomer was prepared by reacting methacryloyl chloride and L-histidine.
  • A series of amide monomers were synthesized by amidation of methacryloyl chloride with amines and grafted onto commercial poly(ether sulfone) (PES) membranes using irradiation from atmospheric pressure plasma (APP).
  • Reaction of methacryloyl chloride with the hydroxyl groups on the surfaces of HEMA/NVP microspheres was performed, leading to the introduction of polymerisable double bonds onto the surfaces of microspheres.
  • Star-shaped poly(d,l-lactide) oligomers with 2, 3 and 6 arms were synthesised, end-functionalised with methacryloyl chloride and photo-crosslinked in the presence of ethyl lactate as a non-reactive diluent.
