Abstract: Process for the production of a thermoplastic polymer comprising segments of a diamide, the process comprising: 1) a first step of preparing a reaction mixture comprising a diamine H2N—Y—NH2 Form. (I), and a diester of a dicarboxylic acid Form. (II) 2) a second step of heating the reaction mixture to a temperature at least 5° C. above the crystallization temperature of the diester and a least 5° C. below the melting temperature of the formed amide (formula III) in the presence of an alkaline or earth alkaline alkoxy catalyst Form. (III) wherein X and Y are the same or different and are an aliphatic group comprising 2-12 carbon atoms or an aromatic group comprising 6-20 carbon atoms, R1 and R2 are the same or different and are an aliphatic group comprising 2-15 carbon atoms and wherein R equals R1 or R2 and are the same or different.

Abstract: A foldable seat for a rollator or a wheelchair includes a first plate and a second plate. The plates are rotatably moveable between an unfolded position and a folded position. A hinge pivotally connects said first plate to said second plate. An exemplary hinge includes at least a first cylinder integral with said first plate and at least a second cylinder integral with said second plate. The seat further includes a locking/unlocking system configured to be actuated by the user so as to lock, respectively unlock, said first and second plates into, respectively from, said unfolded position and/or said folded position. The locking/unlocking system being at least partially lodged inside said first and/or said second cylinder.

Abstract: A method of preparing an anion exchange membrane with anion exchange groups. The method includes polymerizing a first monomer with a functional group selected from the pyridine derivatives with a second monomer selected from the benzene derivatives, such as styrene, to form a copolymer. The copolymer may be crosslinked with a crosslinker. The functional group of the copolymer may be functionalized to an anion exchange group.

Abstract: An apparatus to remove ions, the apparatus including a housing, an inlet to let water into the housing, an outlet to let water out of the housing, a first electrode, a second electrode, a spacer between the first and second electrodes to allow water to flow between the first and second electrodes, and an ion exchange membrane between the first and/or second electrode and the spacer, wherein the membrane has a crosslinked hyperbranched polymer with ion exchange groups.
