Abstract: The present invention relates to a process for producing polyurethane moldings, wherein (a) organic polyisocyanates are mixed with (b) one or more compounds having at least two hydrogen atoms which are reactive toward isocyanate, comprising polyester polyol, (c) blowing agent, (d) catalyst, and (e) propylene carbonate and compounds selected from the group consisting of at least one compound of the general formula (I) and a compound of the formula (II), to give a reaction mixture, introduced into a mold and allowed to react to give a polyurethane molding. The present invention further relates to polyurethane moldings obtainable by such a process and also the use of these moldings as steering wheels, seats, armrests and in particular as shoe soles.

Abstract: The present disclosure relates to a process for preparing polyurethane moldings, including the steps of providing a reaction mixture (M), including at least one polyisocyanate, and at least one component with two functional groups which are reactive towards isocyanates, introducing the reaction mixture (M) into a mold and allowing the reaction mixture (M) to react to form a polyurethane molding. In the first step, at least one additive selected from vegetable oils is added to the mixture (M). The present disclosure also relates to a polyurethane molding obtained or obtainable according to said process and the use of a polyurethane molding according to the invention as sole of a boot or part of a sole of a boot.

Abstract: Disclosed is a process for producing polyurethane boots. The method includes mixing organic polyisocyanates with a combination of polyols, a chain extender, a blowing agent, a catalyst, and optionally other auxiliaries and/or additives. The resulting reaction mixture is introduced, in only one injection, into a mold including a sole and an upper of the mold and allowed to react to form a polyurethane boot. At least one catalyst including a tertiary amine and sebacic acid is employed in a molar ratio of 1:0.19 to 0.27.
