The problem of tinting or discoloration causes the color tone to differ from that of a natural tooth when the catalyst is used for a dental restorative as represented by a composite resin, and reduces the aesthetic value. Impairing the polymerization means that the catalyst cannot be used for ...

For example, for the bishydroxylphenyl propane epoxy resin with epoxy value at 0.51 equivalent/100 g, we use triethylene tetramine as curing...
5 However, this value is for pure MEA undergoing chemisorption and in reality the solution is only 30% aqueous MEA. Therefore, the capacity is reduced to 11%(w/w) for an operational solution. Because a chemical bond is formed, further energy is required to break the bonds during the ...
Conveniently the amide is formed by adding one equivalent of a strong base such as sodium hydride to a solution of the phenol in an inert dry solvent such as dimethylformamide and thereafter reacting with the haloacetamide at a temperature in the range 80° to 120° C. With the amides of ...
