Conclusions

Use of the ternary activating system H3PO4−H2O-PEG is a rather efficient method in the one-stage synthesis of PCA having a degree of polymerization of 150–200.

Formation of amidinium groups during the PCA synthesis process aids in increasing its stability to further polycendensation.

Lowering the moisture content of the PCA melt in the stage of its synthesis to 0.05–0.08% by wt. should eliminate the effect of further polycondensation of the polymer in spinning fibres of almost any assortment.
