Conclusions
-
The possibility of synthesis of fibre-forming block-copolymers of polycaproamide and polyethylene glycol by a reaction of chain lengthening of prepolyamides prepared by cationic polymerization of caprolactam in the presence of 100% H3PO4 has been demonstrated.
-
The data obtained indicate that the block-copolymers of polycaproamide and polyethylene glycol have a structure which ensures an improvement in the coloristic and hygienic properties of the fibre.
