Microstructural Development During Post-Die Drawing

Abstract

This project concerned processing and characterization of materials: polymer-polymer blends and polymer-clay blends. The effort directed at processing of polymer-polymer blends concerned developing new ways to utilize a very high performance polymer polyparaphenylene (PX) by blending it with more easily processable and less expensive amorphous thermoplastics. We discovered that PX when mixed with polycarbonate exhibited a lower critical solution temperature behavior and that for certain compositions, a miscible blend was easily processable between 205-235 degrees Centigrade. Mechanical properties of these blends showed good retention of the outstanding properties of PX but were significantly easier to process. We also studied processing microstructure property relations for blends of a layered silicate and a triblock copolymer.
