✦ Synopsis

Abstract

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.

## Abstract As a new class of biopolymer‐based hybrid materials, the present paper describes the binary blends of a modified chitin and poly(vinyl alcohol) (PVA) which are miscible in the whole range of compositions. The blend films were prepared by the solvent cast method from a homogeneous aqueou
