The introduction into recycled polyethylene terephthalate of 0.5% 1,3-phenylene-bis-oxazoline in the process of extrusion without preliminary drying makes it possible to increase the intrinsic viscosity of the material to 75 mL/g, without any change in its thermophysical properties. The existence of an induction period, during which the additive is less effective, is shown. © 2014 Smithers Information Ltd.
