SAFETY PROFILE Most cured resins have little or no toxicity. If curing is incomplete there may be residues of highly toxic curing agents such as the organic amines m-phenylene diamine, diethylene triamine, tetraethylene pentamine, and hexamethylene tetramine, as well as phthalic anhydride and related compounds. When heated to decomposition they emit highly toxic fumes. See also various epoxy hardeners and POLYMERS, INSOLUBLE. 

If solvent-separated ion pairs or free ions were present, they should produce similar polymer microstructure to that obtained from contact ion pairs since propagation will involve only the allyl anion. There is no evidence for anything other than contact ion pairs in 1 1 lithium complexes with chelating diamines or triamines in hydrocarbon solvents. Only by using excess diamine or the more powerful chelating tetramines can we test the idea. As mentioned previously these are capable of producing some separated ion pairs when the anion is a sufficiently weak nucleophile to be displaced from the lithium by a neutral tertiary amine. With a benzyllithium tetramine complex, both contact and separated ion pair structures were observed spectroscopically. Since allyl and benzyl anions have rather similar charge delocalization, it is reasonable to expect that a tetramine complex of polybutadienyllithium would have similar proportions of contact and separated ion pairs. 

These are widely used because the curing of the epoxies takes place at room temperature. High exothermic temperatures develop during the curing reaction that limit the mass of material that can be cured. The electrical and physical properties of these aliphatic-cured resins had the greatest tendency toward degradation of electrical and physical properties at elevated temperatures. Typical aliphatic amines used include diethylene triamine (DETA) and triethylene tetramine (TETA).

The use of amine chemistry in this application was first developed as an additive to traditional soap-type formulations, where it was found that the lubricity of the fatty acid soap was enhanced. This resulted in the use of fatty amines alone as lubricants without any fatty acids being present. However, simple fatty amines had limited use in this particular field due to their interactions with carbonates, phosphates and sulfates in certain water supplies, thus leading to the formation of insoluble salts. However, it was found the latter could be avoided by using diamines and polyamines (and their salts) in the same formulations. A typical polyamine chain lubricant formulation is shown in Figure 14.32. Examples of the chemistries included under polyamines as chain lubricants include diamines, etherdiamines, triamines and tetramines, with chain lengths of Cn-ig. The acid that is most commonly used to neutralize the polyamine is acetic acid, although other acid types can also be used. The hydrotropes used in this type of formulation can include glycols and alcohols. The...

The aliphatic polyamines most commonly used to cure epoxides are diethyleunine triamine (DETA) and triethylene tetramine (TETA). These are both pungent, low viscosity hquids and they are commonly used with the diglycidyl ether of bisphenol A type resins, where rapid low temperature cures are required. Three other commonly used poly amines are ethylene diamine (EDA), tetramethylene pentamine (TEPA) and diethylaminopropylamine (DEAPA)...
