## Abstract Poly(trimethylene terephthalateβ__co__β2βmethylβ ethylene terephthalate) random copolymers of various compositions were synthesized via traditional twoβstep polycondensation by incorporating of 1,2βpropanediol. The molar composition of trimethylene terephthalate and 2βmethylβethylene te
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
