1H spin diffusion coefficients of highly mobile polymers

Abstract

Advanced solid-state n.m.r. techniques using 1H spin diffusion are useful tools for the non-destructive investigation of polymer morphologies and domain sizes. Calibration measurements of the spin diffusion coefficients are reported in this communication, combining 1H spin diffusion with 13C detection and electron microscopic measurements on a diblock copolymer of known morphology. The spin diffusion coefficients thus determined can now be used for quantitative determination of domain sizes in systems containing both rigid and mobile components.
