Continuous process for drying of N- or amino or ammonium or spirobicyclic ammonium groups containing polymers

A method for drying N- or amino, ammonium or spirobicyclic ammonium group-containing polymers with cationic N-containing groups and counter-ions, in which gelled-out and washed polymers made by polymerisation, crosslinking and optionally alkylation are continuously dried in a fluidized bed with a ga...

Summary:A method for drying N- or amino, ammonium or spirobicyclic ammonium group-containing polymers with cationic N-containing groups and counter-ions, in which gelled-out and washed polymers made by polymerisation, crosslinking and optionally alkylation are continuously dried in a fluidized bed with a gaseous medium under normal or elevated pressure
