Methyl methacrylate mma

Mg microspheres (particle size: 300–500 μm), PMMA prepolymer and N,N-dimethyl-p-toluidine (DMPT) were supplied by Alfa Aesar Chemical Co., Ltd. (Shanghai, China). Benzoyl peroxide (BPO), barium sulfate (BaSO₄), and methyl methacrylate (MMA) were purchased from Sinopharm Chemical Reagent Co., Ltd. (Shanghai, China). Cell Counting Kit-8 reagent (CCK-8) was purchased from Dojindo (Kumamoto, Japan).

Poly(oxyethylene)nonylphenyl ether (IGEPAL CO-520), tetraethoxysilane (TEOS), and 3-mercaptopropylmethyldimethoxysilane (MPTMS) were obtained from Sigma-Aldrich Chemistry, China. 2,4-Dihyoxybenzaldehyde, ethyl acetoacetate, and piperidine were purchased from Energy Chemical Co., Ltd. Phenyl-N-tert-butyl-nitrone (PBN), triallyl isocyanurate (TAIC), 3-bromopropene, cyanoisopropyl dithiobenzoate (CPDB) and isocyanuric acid diallyl ester (IADE) were purchased from Tokyo Chemical Industry, Shanghai. Butane-1,4-diyl bis(3-mercaptobutanoate) (BD-1) and 2,2-bis(((3-mercaptobutanoyl)oxy)methyl)propane-1,3-diyl bis(3-mercaptobutanoate) (PE-1) were supplied by Chembridge International Corp., methyl methacrylate (MMA), tert-butyl acrylate (tBA) and other reagents were supplied by Sinopharm Chemical Reagent Beijing Co., Ltd. Column chromatography was performed by conventional techniques on silica gel (200−300 mesh, Qingdao Haiyang Chemical Co., Ltd.), and silica gel plates were used for TLC analysis. MMA was purified using neutral alumina column to remove the inhibitor. The solvents were dried and purified by standard laboratory methods. All other chemicals were used without any further purification unless otherwise stated.
