technical field

Background technique

Due to the limitations of nylon polymerization technology, the viscosity of slices produced by conventional nylon polymerization equipment (sulfuric acid method) ranges from 2.4 to 2.8, and the viscosity of slices produced by high-viscosity nylon polymerization production lines ranges from 3.2 to 3.4, using melt polymerization. When producing high-viscosity slices, their quality is reduced. The production of high-viscosity slices by solid phase thickening technology is an important production method to obtain high-quality high-viscosity slices.
