ybrid materials represent the family of compounds comprising mixtures of natural and synthetic materials. The study of this field is in a marked expansion since their preparation represents a valid methodology foroptimizing the insufficient properties exhibited by materials integrally formed from naturally-occurring sources. In the present work, we describe soy protein modification by grafting reaction with methyl methacrylate. The reaction was confirmed by Fourier Transform Infrared Analysis andCarbon Nuclear Magnetic Resonance. In addition, films were prepared with the material by heat compression.Films were physically and mechanically characterized by determining contact angle with water, total soluble matter, moisture content, swelling in water, water vapor permeability, tensile strength, elongation at break and Young?s modulus. These measurements suggest that the material increased its hydrophobic character as compared with thatof the control film since marked reductions in water
