【発明の名称】ポリマー材料から揮発成分を除去するための方法及び装置
Document Type and Number:
Japanese Patent JP2003530468
Kind Code:
A
Abstract:
A description is given of a process and an apparatus for the removal of volatile constituents, in particular solvents, monomers or oligomers, from polymer compositions or polymer solutions by evaporating the volatile components from the preheated polymer compositions in the form off free-falling films, strands (4) or foaming liquids in an evaporator system (1). In the process, following partial or complete degassing of the volatile components in the degassing space (9) of the evaporator system (1), the degassed polymer composition (4) is received at the lower end of the evaporator system (1) directly by a discharge delivery device (5) and is discharged, thereby avoiding contact of the polymer with the inside wall of the evaporator system (1).
