1H single point magnetic resonance imaging (SPI)
,, has been introduced in the literature as a method for determining relaxation characteristics of semi-crystalline polymers and for extracting MRI images from such samples. The work presented in the literature to date demonstrates the applicability of this technique. In this work, SPI has been applied to the direct observation of stress-induced changes, temperature induced changes and structural changes in the apparent spin-spin relaxation time, T2*, in polyethylene samples. Several samples prepared under quite different conditions were studied.
