Title (EN) FILMS CONTAINING POLYHYDROXY ACIDS
(FR) FILMS CONTENANT DES ACIDES POLYHYDROXY
Abstract: front page image
(EN)The invention relates to films of blends of polyhydroxy acid and other compatible thermoplastic polymers, and their production by melt processing the materials to obtain uniform composition, and forming the composition into a film of thickness from 0.01 to 2 mm. Such films are useful for conventional film uses where the film is to be discarded into the environment after usage.
(FR)L'invention concerne des films de mélanges d'acide polyhydroxy et d'autres polymères thermoplastiques compatibles, ainsi que leur production par traitement par fusion des matières afin d'obtenir une composition uniforme, et par transformation de la composition en un film d'une épaisseur comprise entre 0,01 et 2 mm. Lesdits films sont utiles dans des utilisations de films classiques dans lesquels ces derniers sont ensuite rejetés dans l'environnement après emploi.
