摘要: The durability of dental resin depends on the stability polymer. neutralizing capacity a basic methacrylate monomer and its chemical were measured using nuclear magnetic resonance (NMR) spectroscopy. Lactic acid solution was titrated with 2-(dimethylamino)ethylmethacrylate (DMAEMA) or 2-hydroxyethylmethacrylate (HEMA) shifts monitored. Addition DMAEMA alters shift proportionally to pH neutralization, whereas HEMA has no impact. Chemical used quantify both change in stability. results demonstrate that neutralization by can be achieved this an NMR assay.
