| Abstract Scope |
While polymer backbone chemistry may play a limiting role in polymer performance, control of morphology through processing enables the use of a given chemistry for wide range of applications. One example of this is the use of high density polyethylene in grocery bag and the use of the same chemistry to provide high strength, high modulus fibers used in ballistic protection helmets. While one usually associates high modulus polyethylene products with ultra-high molecular weight and gel spinning, it was shown by the late Professor Ian M. Ward that similar moduli could be obtained from moderate molecular weight polyethylene and melt spinning. Recent work at MIT showed that ultra-oriented polyethylene nanofibers showed Griffith behavio. At a time where the ecological impact of plastics is under scrutiny, the use of a given chemistry over a wider range is applications is again becoming attractive and presents opportunity for the future. |
