  Abstract

Melting temperature of the poly(ether-ester) copolymers are generally around 200 oC and are suitable for moisture barrier in active sportswear, but higher melting temperatures are required for them to be used in personal protective clothing. In an attempt to obtain higher melting poly(ether-ester) copolymers, copolymerization of bishydroxybutylnaphthalate and poly(ethylene glycol)-b-poly(propylene glycol)-b-poly(ethylene glycol) tri-block copolymers (EPE) was carried out to obtain poly(butylene 2,6-naphthalate)/EPE copolymers with poly(butylene 2,6-naphthalate) (PBN) as hard segments and EPE as soft segments. PBN/EPE copolymers containing different amounts of EPE (0, 5, 10, 20 and 30 wt%) of different molecular weights (1100, 2000, 2800 and 5800) were prepared. Composition analysis, solution viscosity and density measurements were made. The composition of copolymers determined from 1H-NMR spectra were similar to feed composition.
