ΣΥΝΤΟΜΗ ΠΕΡΙΛΗΨΗ
Poly(ethylene terephthalate) (PET) is subjected to reactive extrusion processing (REX) in the presence of a chain extender additive, consisting of pyromellitic dianhydride, a polyol and a catalyst. Rheological characterization (solution and melt viscosity) is used to predict the evolving molecular size and architecture of PET during REX, as a function of additive concentration, c.
