Biodegradable starch acetate plastics are synthesized from whole agricultural flours and acetylating agents, without the use of solvents. The process includes a low temperature, staged addition of catalyst to the reactant mixture. The resultant polymers may be blended with other polymers, and biodegradable plasticizers as well as other materials. Plastics with a wide range of colors and physical properties are produced using natural coloring agents, agricultural fillers, and product blending. |
