Continuous process for the hydrolytic production of polycaprolactam by tempering unextracted granular polymer material with moist inert gas |
摘要 |
A process for tempering unextracted polycaprolactam is disclosed which results in polycaprolactam having suitable physical and chemical properties for melt extrusion and spinning, without the need for conventional solvent/water extraction and drying of crude granules.
