(EN) BIODEGRADABLE POLYESTER COMPOSITIONS WITH NATURAL POLYMERS AND ARTICLES THEREOF
(FR) COMPOSITIONS DE POLYESTER BIODEGRADABLES RENFERMANT DES POLYMERES NATURELS ET ARTICLES A BASE DE CES COMPOSITIONS
Abrégé
(EN) Compositions of the invention include particular hydroxy-functional polyesters and a natural polymer. Among articles that can be made from such compositions are those with sufficiently strong tensile strengths as to form disposable utensils. However, the compositions are more environmentally friendly than commodity plastics such as polyethylene or polystyrene. Starches are particularly preferred as the natural polymers for inclusion in the compositions.
(FR) L'invention concerne des compositions renfermant des polyesters hydroxy-fonctionnels particuliers et un polymère naturel. Parmi les articles pouvant être fabriqués à partir desdites compositions figurent ceux qui doivent avoir une résistance à la traction suffisamment élevée, comme dans le cas des ustensiles jetables. Néanmoins, lesdites compositions présentent moins de danger pour l'environnement que les matières plastiques de base du type polyéthylène ou polystyrène. De préférence, on utilisera en particulier des amidons comme polymères naturels destinés à être incorporés dans les compositions considérées.
