## Abstract **Summary:** Fully‐biodegradable bacterial poly(3‐hydroxybutyrate) (PHB)/chemosynthetic poly(vinyl alcohol) (PVA) blend films with compositional gradient from one surface to the other surface of the films were prepared by a dissolution‐diffusion technique. Three kinds of PVA samples, hi

Compatibility of a crystalline/crystalline polymer blend, poly(viny1 alcohol) (PVA)/poly(3hydroxybutyrate) (PHB), was studied by high-resolution solid-state 13C-NMR spectroscopy. The 'H T1 measurement demonstrated that both the compatibility and the domain size depend on the composition of the blen
## Abstract The extens of crystallization of poly(3‐hydroxybutyric acid) (P(3HB)) in blends of P(3HB) with stereoregular poly(vinyl alcohol) (PVA) have been studied by means of infared spectroscopy. The degree of crystallinity of P(3HB) was found to decrease by blending with atactic PVA when PVA wa
