摘要： Formed articles comprising destructurized starch, an ethylene-acrylic acid copolymer and a product of the interaction of starch and ethylene-acrylic acid copolymer wherein the starch not bound to the copolymer is in the form of particles having sizes below 1 micron. The water content of such articles is lower than the one usually present in the starch. Said formed articles can also contain urea in an amount no higher than 30% by weight and/or ammonia in an amount not higher than 0.5% by weight. The process for obtaining such articles comprises the steps of extruding starch, an ethylene-acrylic acid copolymer and optionally water, urea and/or ammonia at a temperature ranging from 90.degree. to 150.degree. C., reducing the water content to values lower than 6% by weight and injection molding or extrusion blowing the resulting composition.

摘要： In order to prepare a starch-based composition usable for the production of articles of biodegradable plastics material, a starch is mixed in a heated extruder with a high-boiling plasticizer and a destructuring agent for a time sufficient to cause the starch to be destructured, in dependence on the destructuring agent used, at a temperature below the boiling point of the plasticizer used and between 120.degree. and 170.degree. C.The composition thus obtained is particularly suitable for the formulation of polymer mixtures with polymers which have relatively high melting points, since it can be processed at temperatures higher than 120.degree. C. and is suitable for extrusion at low pressure with these polymers. In particular, compositions thus obtained and mixed with polyvinyl alcohol and/or ethylene vinyl alcohol are suitable for the formation of films by blow-extrusion, since they have the desired characteristics of mechanical strength and resistance to tearing and perforation, or for the formation of articles finished by injection moulding, thermoforming or blowing.

摘要： A polymer composition usable for the production of articles of biodegradable plastics material includes an ethylene/vinyl alcohol copolymer and destructured starch. Preferably, the composition is obtainable by mixing the ethylene/vinyl alcohol copolymer, in a heated extruder, with a starch component constituted by a destructured starch composition produced beforehand by mixing starch with a high-boiling plasticizer, such as glycerine and a destructuring agent, preferably constituted by urea, in an extruder. Alternatively, the composition can be obtained by mixing the ethylene/vinyl alcohol copolymer with starch and a plasticizer in an extruder, with water added as appropriate and possibly with a suitable destructuring agent.The composition is particularly useful for the production of films with good resistance to perforation and tearing and molded articles with improved mechanical strength. The products made from this composition are also good oxygen and carbon dioxide barriers.
