摘要：

Advanced solid-state n.m.r. techniques using H-1 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 H-1 spin diffusion with C-13 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.
