This kind of resin can be prepared by polycondensation of binary amine and binary acid, or by ring opening polymerization of lactam formed after amino acid dehydration. Unlike PS, PE and PP, PA does not soften gradually with the increase of heating temperature, but softens in a narrow temperature range close to the melting point. The melting point is very obvious, such as nylon 6 melting point: 215-225 ℃. Once the temperature is reached, flow occurs
