Poly(ethylene terephthalate) modified with a dianhydride (PET-anhydride) was melt-blended with a liquid crystalline copolyester (Vectra A) in the presence of a small amount of a liquid crystalline polyhydroxyether. The mechanical properties of a blend consisting of PET-anhydride/Vectra A/polyhydroxy
## Abstract Poly(ethylene terephthalate)/__p__‐hydroxybenzoate (PET/PHB) copolymer materials have relatively low melt viscosity because of the 60 mol % PHB material having a value that is lower by approximately two orders of magnitude than the value for PET homopolymer. The structure development du
A series of copolyesters were prepared by the incorporation of p-hydroxybenzoic acid (HBA), hydroquinone (HQ), and terephthalic acid (TA) into poly(ethylene terephthalate) (PET). On the basis of viscosity measurements, high molar mass copolyesters were obtained in the syntheses, and 1 H-NMR analyses
