Molecular, structural and thermal analyses evidenced that copolymerization has an impact on solidstate properties. The presence of the two different polymer blocks allows the obtaining of a tenacious material with high melting temperature, characterized by lower elastic modulus and improved elongation at break.
The copolymer was obtained through chain extension of two hydroxyl-terminated prepolymers prepared by polycondensation: poly(hexamethylene furanoate) PHF-OH, and poly(triethylene furanoate) PTEF-OH. The chain extended homopolymer PHF-CE was also synthesized for sake of comparison.

Abstract
The copolymer was obtained through chain extension of two hydroxyl-terminated prepolymers prepared by polycondensation: poly(hexamethylene furanoate) PHF-OH, and poly(triethylene furanoate) PTEF-OH. The chain extended homopolymer PHF-CE was also synthesized for sake of comparison.File in questo prodotto:
