Crosslinked methyl methacrylate/ethylene glycol dimethacrylate polymer compounds with a macroazoinitiator

A silane-containing diamine, bis(p-aminophenoxy) diphenylsilane (BADPS), was prepared by the condensation of p-aminophenol with dichlorodiphenyl silane in the presence of triethylamine. Then, BADPS was condensed with 4,4-azobis(4-cyanopentanoyl chloride) to prepare macroazoinitiators containing sila...

Description
Summary:A silane-containing diamine, bis(p-aminophenoxy) diphenylsilane (BADPS), was prepared by the condensation of p-aminophenol with dichlorodiphenyl silane in the presence of triethylamine. Then, BADPS was condensed with 4,4-azobis(4-cyanopentanoyl chloride) to prepare macroazoinitiators containing silane units (Si-MAIs). A series of poly(methyl methacrylate) gels containing silane were derived by the solution free-radical crosslinking copolymerization of methyl methacrylate and ethylene glycol dimethacrylate monomers initiated by these macroazoinitiators at a total monomer concentration of 6 mol/L and 80°C. Si-MAIs were characterized with ¹H-NMR and ¹³C-NMR spectroscopy, and the structural characteristics of the gels were also examined.
