FIELD: process engineering.
SUBSTANCE: thread is produced by using multi-channel feed pipeline to feed polymerised monomer and polymerisation solvent. Said pipeline features special design of inner (11a) and outer (11b) channels arranged alternating relative each other and designed to feed either aromatic diatomic chloride A or aromatic diamine dissolved in polymerisation solvent B into polymerisation reactor (20) via appropriate channel (inner or outer) (11a) or (11b). Proposed invention boasts efficiency in uniform and homogeneous polymerisation over the entire space of polymerisation reactor (20) that results in reduction of deviances in polymerisation degree, since polymer monomers are mixed together to produce their good interaction directly after introducing them into reactor (20).
EFFECT: produced thread features narrow range of poly dispersity index, increased visible size of crystal, higher strength and modulus.
