Patent

CA 2341173

A method of making a biodegradable polymer composition including the steps of providing a first component being either one of a thermoplastic poly(hydroxy ester ether) or a synthetic, hydroxy-functional polymer and providing a second component being a natural polymer. The method includes the steps of mixing the first component and second component together to form a mixture, compounding the mixture, and pelletizing the compounded mixture to form pellets of a biodegradable polymer composition.

L'invention concerne un procédé de préparation de compositions polymères biodégradables, consistant à fournir un premier composant, celui-ci étant soit un poly(hydroxy ester éther) thermoplastique, soit un polymère synthétique à fonction hydroxy, et à fournir un second composant celui-ci étant un polymère naturel. Ce procédé consiste à mélanger le premier composant et le second composant afin de former un mélange, à amalgamer ledit mélange, et à former des granulés d'une composition polymère biodégradable à partir dudit mélange amalgamé.
