Efficient method for recycling poly(ethylene terephthalate) to poly(butylene terephthalate) using transesterification reaction

Abstract

When this article was printed, there were three typographical errors in it. The errors are corrected below: On page 3722, the section head in the left column should read: Effect of PET : BD ratio on THF formation in the presence and absence of externally added catalyst On page 3727, lines 9–14 in the right column should read: Mechanical properties The mechanical properties, namely, tensile strength and unnotched Izod impact strength of PBT obtained upon transesterification of scrap PET, were determined. These results are shown in Table XI. These values compare well with virgin PBT. On page 3728, reference 2 should read: 2. (a) Asaba, F.
