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 aqueous solution of PVA and a chitin derivative having poly(2‐methyl‐2‐oxazoline) side chains. Miscibility between PVA and poly(2‐methyl‐2‐oxazoline) homopolymer was also revealed. Differential scanning calorimetry and FT‐IR analyses were used to investigate the blends.
