Magic-angle spinning proton NMR imaging of polybutadiene/polystyrene blends.
A simple method of obtaining 1H NMR images of solids is introduced which relies on magic-angle spinning for line narrowing. The spatial resoln. of the method is <50 mm. The method is insensitive to many instrumental artifacts and only requires slight modifications of com. equipment. Images are shown of a dynamically stressed isoprene rubber phantom and of polybutadiene in 2 polybutadiene-polystyrene blends.
