Process temperature profiles of a two-component rigid poly(urethane-isocyanurate) foam system were studied and compared with the predictions of a onedimensional numerical simulation. This model is based on experimentally determined thermophysical properties including thermal diffusivity, enthalpy of

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
