The chain extension reaction in poly(butylene terephthalate) (PBT) melt was studied in detail. A high-reactivity diepoxy, diglycidyl tetrahydrophthalate, was used as a chain extender that can react with the hydroxyl and carboxyl end groups of PBT at a very fast reaction rate and a relatively high te

## Abstract The effectiveness of the reactive extrusion technique was investigated for poly(ethylene terephthalate) to promote the concept of closedβloop recycling, that is, the reuse of waste material in the initial application. More specifically, a chainβextender system, consisting of pyromelliti
Molecular weight increase via chain extension reactions of poly(ethylene terephthalate) with commercially available diepoxides was studied in a custom-made laboratory scale reactor and a Brabender rheomixer under reactive blending conditions. The products were characterized by carboxylic end group a
