Casein was grafted with mixtures of acrylonitrile (AN) and n ‐butyl methacrylate ( n ‐BMA). The mole ratios of AN: n ‐BMA were 0.9:0.1 and 0.8:0.2. The mechanical properties of the grafted casein films were studied under uniaxial and biaxial stress conditions. A reduction in longitudinal stress and elongation at break was observed with the simultaneous application of lateral stress. Scanning electron micrographs of the stretched films (uniaxial and biaxial stress) are also presented.
