The mechanism of steric network formation in the diglycidyl ether reactions with diamines

Studies of the reaction of the first and second members in a homologous series of diglycidyl ethers of diphenylolpropane with m-phenylenediamine, carried out with determinations of the original components and of epoxy group conversion, were used to propose a scheme according to which a steric network forms during the early process stages. A link was found to exist between the chemical composition of the original ethers and their conversion rates, as well as with the consecutive reactions of network formation.
