METHOD OF PROCESSING MONOMER, PREPOLYMER, POLYMER OR RESPECTIVE MIXTURE Russian patent published in 2015 - IPC D01D1/02 

FIELD: chemistry.

SUBSTANCE: invention relates to method of processing monomer, prepolymer, polymer or respective mixture, in particular, in order to obtain spinning solution for production of polymer fibres, in particular para-aramide fibres. In claimed method monomer, prepolymer, polymer, additives or respective mixture are mixed with solvent, mixed, melted, homogenised and/or subjected to degassing, after that, discharged, with said operations, at least, partially, being carried out in one reactor. In accordance with invention monomer, prepolymer, polymer or respective mixture by means of device for forced loading is forcibly loaded into reactor, with device for forced loading being represented by transporting device, located in front of reactor, containing at least one transporting screw with different steps, into which monomer, prepolymer or respective mixture are supplied and in which force or pressure directed towards reactor is created. Product is pressed and compacted, then loaded into reactor without leaving almost any free space. Respective device is used for claimed method.

EFFECT: product in reactor is processed more efficiently, with simultaneous increase of finished product quality.
