Hi Sir, I would like to know that we produce epoxy resin or polyurethanes using polycondensation. But nylon 6,6 is also produced by polycondensation. So, why Nylon6,6 is thermoplastic and epoxy or polyurethane are thermosetting resins in liquid form.

Hello Pavan, Let me explain it here: Polycondensation is a method of polymerization. It can be employed in synthesizing different polymers (e.g. containing different monomers). Simply, you have monomers, that react via polycondensation, and finally, a polymer is produced. However, this polymer can be either a thermoset or a thermoplastic. It means that if the synthesized polymer contains "unsaturated groups" like epoxies, C=C bonds, etc. it can further react. Here, we have thermosets as the polymeric chains can react further to produce a network. this is what we call crosslinking. On the other hand, in thermoplastics, like Nylon 6,6, or PET, there is no unsaturated group available for further reaction. After the polymerization, the polymeric chains have no ability to be cross-linked. Here, we have long chains of connected monomers, but the chains are not connected.
