There are many varieties of PA, such as PA6, PA66, pall, PA12, PA46, PA610, pa612, PA1010, etc., and many new varieties of semi aromatic nylon PA6T and special nylon developed in recent years. Nylon-6 plastic products can be prepared by using metal sodium and sodium hydroxide as the main catalyst and n-acetylcaprolactam as the cocatalyst, so that δ - caprolactam can be directly prepared by anionic ring opening polymerization in the model, which is called cast nylon. It is easy to make large plastic parts by this method.
