Abstract Cross polarization/magic angle spinning (CP/MAS) 13 C n.m.r. measurements have been performed at room temperature for poly(vinyl alcohol) (PVA) films with different tacticities to obtain information about the structure and hydrogen bonding in the crystalline and non-crystalline regions. 13 C spin-lattice relaxation analyses have revealed that three components exist for each sample, with different spin-lattice relaxation times T 1C , which are assignable to the crystalline, less… CONTINUE READING
