Polyamide polyethylene glycolpolyamide block copolymer |
摘要 |
A linear block copolymer of regular structure, comprising polyamide and polyethylene glycol blocks. Two polyamide blocks (A) are bound through an intermediate polyethylene glycol block (B) according to a structural scheme (A-B-A). Fibers exhibiting a high moisture absorption strong mechanical properties and a high dyeability. Textile manufactured goods comprising said fibers. A process to obtain said block copolymer, through the preparation of a polyamide (A) and a polyethylene glycol (B), and condensation of polyamide (A) and polyethylene glycol (B) so as to obtain a (A-B-A) structure.
