Polypeptide‐synthetic polymer hybrids, 1. Miscibility of poly(vinyl alcohol) with poly(sodium α,β‐D,L‐aspartate)

The present paper describes materials of polypeptide‐commodity polymer hybrids from poly(vinyl alcohol) (PVA) and poly(sodium α,β‐ D , L ‐aspartate) ( 1 ). Miscible blend films of polypeptide 1 and PVA were prepared by the solvent‐cast method from a homogeneous aqueous solution. Differential scanning calorimetry. Fourier transform infrared, and scanning electron microscopy combined with energy dispersive X‐ray spectroscopy (EDX) were used to investigate the blends. It was revealed that 1 and PVA are miscible in a wide range of compositions.
