Latest Patents

Elvina holds a patent for a process for preparing highly viscous polyhexamethyleneadipamide. This process involves postpolycondensing the melt of a polymer with a relative viscosity of 2.5-2.7 in a twin-screw extruder. The extruder features degassing zones and closely meshing screws that turn in the same direction. The polymer melt undergoes polycondensation through treatment in multiple zones of alternatingly elevated and reduced pressure. In the elevated pressure zones, steam superheated to the temperature of the melt is supplied, while in the reduced pressure zones, the input vapor phase and water of condensation are drawn off. The temperature of the melt is uniformly raised from 260°C-280°C in the first zone to 280°C-310°C in the last zone.
