N-methoxymethyl nylon

There exists a large number of other solvent-based adhesives derived from synthetic polymers that are soluble in organic solvents. For example, substituted nylons (aliphatic polyamides)—typically, N-methoxymethyl nylons—are soluble in some alcohols and alcoholic mixtures and have been used to provide solution adhesives with good rust resistance. Such soluble nylons may be compounded with many thermosetting polymers to improve their properties to yield such outstanding characteristics as their resilience and peel strength. 

FIGURE 9.16 N-Methoxymethyl nylon is made by reacting nylon 66 with formaldehyde and methanol in acid conditions. In acidic (or alkaline) conditions, this can revert to nylon by loss of the hydoxymethyl group or can cross-link to form an insoluble material. 

Mannich reaction on nylon is carried out according to a method consisting of the preliminary reaction with formaldehyde/methanol followed by amine condensation on the resultant N-methoxymethyl derivative." ...
