    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.
