The relationship between the polymerization rate of various acrylates and methacrylates containing acid groups and their ability to hydrogen bond has been investigated by real-time infrared spectroscopy. The polymerization rate dependence on temperature of the acid-based acrylates and methacrylates is reduced compared to traditional (meth)acrylates with no groups capable of hydrogen bonding. For two of the acid containing monomers, polymerization rates actually decreased with an increase in temperature.
