| Abstract: | Chain extension for PET is studied by melt-extrusion using 1,3phenylene-bis(2-oxazoline ) (PBO) as an extender.The effect of the addition quantity of PBO, the temperature of extension and the speed of extrusion on the extension reaction is investigated. The effect of using PBO and phthalandione as a combinative extender on the extension is tested. |
