WebNylon 6 is produced by the hydrolytic or catalytic ring opening polymerization of caprolactam to obtain epsilon-aminocaproic acid, which readily condenses to nylon 6 at high temperatures and a vacuum (to remove the water condensate) to high-molecular-weight polymer (Figure 7.48). WebNylon 6,10, which is the product of a condensation polymerization, will be prepared in this investigation. One of the most important kinds of nylon is nylon 6,6. It was invented in the late 1930s in the United States by Wallace Carothers who was working for DuPont. Nylon can be synthesized by a condensation reaction.
