Domain Size Determination of Poly(phthalamide )/Poly-(dimethylsiloxanes) Block Copolymer by 1H Solid-State Spin Diffusion NMR Spectroscopy

1H solid-state spin diffusion NMR spectroscopy was applied to calculate domain sizes of separated phases in poly(phthalamide )/poly-(dimethylsiloxane) copolymers. To initiate spin diffusion, the dipolar filter technique was used. The correlation between longer PDMS chains in the copolymer and bigger domains of the PDMS phase could be shown
