Abstract: The present application relates to a process for preparing polyesters comprising reacting a dicarboxylic acid with butanediol in the presence of a catalyst, wherein in the process an aluminosilicate is present, as well as the use of aluminosilicates in such a process.

Abstract: A packaging article (2) comprising a blister shell (6) and a blister card (4); the blister card (4) comprises a first layer (12) and a second layer (14) arranged to form a groove; wherein the blister shell (6) is configured to be held by the groove and the blister shell (6) is slidable along the groove to remove the blister shell (6) from the blister card (4).

Abstract: There is described a process for preparing a biodegradable polyester from an aromatic dicarboxylic acid, an aliphatic dicarboxylic acid and a diol where in a first reaction step the aromatic acid is esterified with the diol, and in a second reaction step the aliphatic acid is added to the reaction mixture. Furthermore, there is described an apparatus for carrying out this process.

Abstract: A process for reducing the amount of hydroxyl-end-groups of a polyester, wherein the polyester is prepared from at least one dicarboxylic acid and at least one dihydroxy alcohol, and at least one additive selected from the group consisting of carboxylic acid anhydride and mono-isocyanate, and wherein the additive is added during a step of prepolycondensation and/or during a step of polycondensation and/or after a step of polycondensation.

Abstract: A deformable container that is suitable for dispensing dishwasher machine cleaner in an automatic dishwasher. The container defines an interior volume for a fluid, and includes an outlet fluidly connected to the interior volume. A portion of the container is deformable upon reaching a predetermined temperature to reduce the size of the interior volume for forcing the fluid out from the container via the outlet. A seal at the outlet is openable by the fluid forced from the interior volume when the size of the interior volume is reduced to control the escape of fluid from the container.
