Abstract The present invention refers to a composition comprising: (a) 5-95wt% of a poly(alkylene carbonate), wherein said poly(alkylene carbonate) has a glass transition temperature equal to or lower than 30ºC and a number average molecular weight higher than 15,000 Da; and (b) 95-5 wt% of poly(alkylene carbonate), wherein said poly(alkylene carbonate) has a glass transition temperature higher than 30ºC. It also refers to a method for producing said composition as well as to its use for preparing adhesive formulations with improved thermal stability and adhesion properties. La présente invention concerne une composition comprenant : (a) 5 à 95 % en poids d'un polycarbonate d'alkylène, ledit polycarbonate d'alkylène présentant une température de transition vitreuse inférieure ou égale à 30°C et un poids moléculaire moyen en nombre supérieur à 15000 Da ; et (b) 95 à 5 % en poids de polycarbonate d'alkylène, ledit polycarbonate d'alkylène présentant une température de transition vitreuse supérieure à 30°C. L'invention concerne également un procédé de production de ladite composition ainsi que son utilisation pour préparer des formulations adhésives comportant des propriétés de stabilité thermique et d'adhésion améliorées.
