Expired - Fee Related Application number DE8585870185T Other languages German (de) English (en) Inventor James Delvin Gabbert Ross Melvin. British Patent 763,746 describes a process forthe continuous polymerization of ε-caprolactam in which polymerization is carried out in a sealed, completely filled vessel at elevated temperature and elevated pressure in the presence of not more than 1% of water as the sole agent for accelerating the reaction. Since this process operates without chain stoppers and must be followed by direct spinning, it is not suitable for universal use. The process is carried out at pressures of from 5 to 35.
