We have synthesized a new block copolymer with poly (ethylene terephthalate) as the hard segment and poly olefine as the soft segment by the condensation of terephthaloyl chloride, hydrogenated α, ω-dihydroxy polybutadiene and ethylene glycol. This block copolymer was characterized by 1H and 13C NMR and FT-IR. Quantitative estimations of the contents of block segments have been carried out by 1H NMR. The effect of the addition of this block copolymer in PET/HDPE polymer blends was investigated.
