    摘要： The invention relates to an alloy composition possessing improved properties of mechanical resistance. The composition contains a starch, which is preferably plasticized, and a polymer which acts as coupling agent which is chosen from the group consisting of polyolefins modified by chemical functional groups which are active toward the hydroxyl functional groups of starch. Generally, the composition also contains a thermoplastic polymer. The invention also relates to the process for preparing this composition and the use of these compositions for the manufacture of films intended for the paper market and for packages made from biodegradable plastic.

    摘要： A mixture is produced, comprising from 50 to 95% by weight of at least one vinyl chloride-based resin, from 1 to 20% by weight of at least one olefin-based resin, from 1 to 20% by weight of a copolymer of ethylene and vinyl acetate which has a vinyl acetate content of between 10 and 35% and from 2 to 40% by weight of a copolymer of ethylene and vinyl acetate which has a vinyl acetate content of between 60 and 95%, and the product thus obtained is then processed.The process makes it possible in particular to produce sheets which have good mechanical properties and which have a remarkable transparency.
