| Abstract: | The twin screw reactive extrusion process for nylon 6 inland was introduced. By anion rapid polymerization of caprolactam,high performance nylon 6 was produced with direct reaction and forming. This process had advantages of continuous operation, short period, and good performance of products.Comparing with nylon-6 produced by traditional process, the product produced by reactive extrusion had superior performance such as stretch strength, bending strength and notch impact, and the relative viscosity can reach to 4.2～5.0. The technical properties of twin screw reactive extruder were introduced briefly. |
