Blends of poly(Me methacrylate) (I) with poly(vinylidene fluoride) (II) are studied by solid-state 19F-13C CPMAS NMR. Data were acquired under simultaneous proton and F dipolar decoupling. These expts. showed that I-II blends with wt. ratios 80:20, 60:40, 40:60, and 20:80 were mixed at the mol. level. The av. distance between I C=O and OCH3 carbons and II fluorines in all bands was 2.6-3.1 .ANG..
