摘要： Spent polyurethanes are returned to the value chain by hydrogenating the spent polyurethanes in a hydrogen atmosphere in the presence of at least one homogeneous transition metal catalyst complex, wherein the transition metal is selected from metals of groups 7, 8, 9 and 10 of the periodic table of elements according to IUPAC, to obtain a polyamine and a polyol. The hydrogenation is carried out at a reaction temperature of at least 120° C. in a non-reducible solvent having a dipole moment of 10-1030 C·m or less.

摘要： The present invention relates to a polymer film (P) contacting at least one copolyamide. The copolyamide is prepared by polymerizing a first monomer mixture (M1), containing at least one C4-C12 dicarboxylic acid and at least one C4-C12 diamine, and a second monomer mixture (M2) containing at least one C32-C40 dimer acid and at least one C4-C12 diamine. The present invention further relates to a process for producing the polymer film (P) and to the use of the polymer film (P) for high-temperature applications.
