Synthesis of Segmented Block Copolymers Based on Polyamide-1010 and Polytetramethylene Glycol

Abstract

Segmented block copolymers (PA1010-b-PEG) based on α,ω-dicarboxy-polyamide-1010 (PA1010dC, = 1000, 2000, 3000 and 5000) and α,ω-dihydroxy-polytetramethylene glycol (PEG, = 1000, 2000) were synthesized by melt condensation. Various block copolyamides with different block lengths of the hard and soft segments were obtained, and their composition and block lengths were determined via FT-IR and 1H-NMR.
