Abstract

L'invention concerne des produits à base de polymères doux et élastiques obtenus par étirement d'une composition comprenant un copolymère polyhydroxyalkanoate biodégradable renfermant au moins deux unités monomères se répétant de manière aléatoire. La première unité monomère, qui se répète de manière aléatoire, possède une structure (I), dans laquelle R<1> représente H, ou un groupe alkyle en C1 ou C2, et n prend la valeur de 1 ou 2. La seconde unité monomère, se répétant de manière aléatoire, est différente de la première et possède une structure (II), dans laquelle m prend la valeur de 2 à environ 9. Au moins environ 70 % en mole de copolymère sont constitués d'unités monomères se répétant de manière aléatoire et présentant la structure de la première unité monomère (I). Les produits de la présente invention présentent des combinaisons avantageuses de douceur et d'élasticité tout en conservant leur résistance.
