Abstract: front page image
(EN)The present invention provides, among other things, extruded blends of aliphatic polycarbonates and polyolefins. In one aspect, provided blends comprise aliphatic polycarbonates such as poly(propylene carbonate) and a lesser amount of a crystalline or semicrystalline polymer. In certain embodiments, provided blends are characterized in that they exhibit unexpected improvements in their elongation properties. In another aspect, the invention provides methods of making such materials and applications of the materials in applications such as the manufacture of consumer packaging materials.
(FR)La présente invention concerne, entre autres choses, des mélanges extrudés de polycarbonates aliphatiques et de polyoléfines. Dans un aspect, l'invention propose des mélanges comprenant des polycarbonates aliphatiques tels que les polycarbonates de propylène et une moindre quantité d'un polymère cristallin ou semi-cristallin. Dans certains modes de réalisation, les mélanges proposés sont caractérisés par des améliorations inattendues de leurs propriétés d'élongation. Dans un autre aspect, l'invention propose des procédés de fabrication de tels matériaux, et des utilisations de ces matériaux, notamment pour la fabrication de matériaux d'emballage de biens de consommation.
