Modeling and experimental investigation of melamine-formaldehyde polymerization

摘要: Polymerization of melamine with formaldehyde has been studied at high temperatures and molar ratios of monomers similar tothose used in industry. Melamine dissolves in formaldehyde slowly and ionizes in the reaction mass to some extent. The polymer formation is a complex process of polymerization of the un-ionizedmolecules of melamine. Using the functional group approach, we have modeledthe batch polymerization and determined the rate constants through curve-fitting. We find that the rate constants are a function of …
