Back Cover: The graph shows the morphology, as visualized by polarized light microscopy, of neat poly(butylene adipate) (PBA) crystallized at 28 °C, giving irregularly scattering ring bands in spherulites. Ring bands in PBA are seen only at a very narrow range of Tc = 29–31 °C (3 °C range). PBA/poly(vinyl acetate) and PBA/poly(hydroxyether of bisphenol A) blends collectively prove that the ring bands cannot be attributed to α+β polymorphism. For further details, see the article by G. Lugito, and E. M. Woo* on page 2228.
