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.[1] - Functional monomer was prepared by reacting methacryloyl chloride and L-histidine.[2] - 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).[3] - 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.[4] - 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.[5] |
