摘要
用双口恶唑啉化合物作扩链剂,在双螺杆挤出机中进行聚酯扩链反应。考察扩链剂用量、反应温度、螺杆转速对扩链反应的影响。并与苯酐联用,测定了联用效果。
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.
