## Abstract Poly(butylene 2,6βnaphthalate) (PBN)/poly(ethylene glycol) (PEG) copolymers were synthesized by the twoβstep melt copolymerization process of dimethylβ2,6βnaphthalenedicarboxylate (2,6βNDC) with 1,4βbutanediol (BD) and PEG. The copolymers produced had different PEG molecular weights and

Random copolymers of poly(ethylene terephthalate) (PET) and poly(ethylene 2,6-naphthalate) (PEN) were synthesized by melt condensation. In a series of thin, solvent cast films of varying PEN content, acetone diffusivity and solubility were determined at 35Β°C and an acetone pressure of 5.4 cm Hg. The
The effects of transesterification on the miscibility of poly(ethy1ene terephthalate)/ poly(ethy1ene 2,6-naphthalate) were studied. Blends were obtained by solution precipitation a t room temperature to avoid transesterification during blend preparation. The physical blends and transesterified produ
