Preparation of Novel Super-tough Poly (ethylene terephthalate) Engineering Plastic

摘要

This research focused on a new kind of super-tough engineering plastic based on waste PET bottles chips. The processing technology of this polymer alloy is briefly introduced. This polymer alloy is prepared by low temperature solid-state extrusion and reactive extrusion. Via the reaction among chain extender and PET chips, three-dimension network was formed and the crystal structure in the bottle blowing process was maintained in the new blends. Toughening mechanism was studied, and the relationship between properties and the structure was analyzed.
