| 中文摘要 | blends of crystallizable poly(vinyl alcohol) (pva) with poly(n-vinyl-2-pyrrolidone) (pvpy) were studied by c-13 cross-polarization/magic angle spinning (cp/mas) n.m.r. and d.s.c. the c-13 cp/mas spectra show that the blends were miscible on a molecular level over the whole composition range studied, and that the intramolecular hydrogen bonds of pva were broken and intermolecular hydrogen bonds between pva and pvpy formed when the two polymers were mixed. the results of a spin-lattice relaxation study indicate that blending of the two polymers reduced the average intermolecular distance and molecular motion of each component, even in the miscible amorphous phase, and that addition of pvpy into pva has a definite effect on the crystallinity of pva in the blends over the whole composition range, yet there is still detectable crystallinity even when the pvpy content is as high as 80 wt%. these results are consistent with those obtained from d.s.c. studies. |
