FIELD: chemistry.
SUBSTANCE: invention relates to a method of processing a regenerated polycondensation polymer for repeated use. The method involves supply of the used polycondensation polymer, selected from polyester or polyamide in molten state in a polymerisation container fitted with a porous plate having from 5 to 105 pores, where the said plate has cross sectional area from 0.01 to 100 cm2 and thickness from 0.1 to 300 mm. After releasing the polycondensation polymer through pores of the porous plate, the degree of polymerisation of the polycondensation polymer is increased at low pressure or in an atmosphere of an inert gas at low pressure of 50000 Pa or less while simultaneously lowering the polycondensation polymer along the carrying body in any form of wire, chain, grid, cubic lattice, thin film, porous plate and column formed as a result of piling filler of the right shape.
EFFECT: increased efficiency of the method combined with low expenses while preserving high quality of the processed polymer at the same time.
