    Abstract: The present invention relates to a process for producing a composition (I) at least comprising a compact thermoplastic polyurethane (P1), comprising the providing of at least one compact thermoplastic polyurethane (P1) or a reaction mixture for production of a compact thermoplastic polyurethane (R-P1), the adding of at least one compound (N) that has a conjugated, nitrogen-containing aromatic structure as nucleating agent to the at least one thermoplastic polyurethane (P1) or to the reaction mixture for production of a compact thermoplastic polyurethane (R-P1), wherein the compound (N) is a solid; and the mixing of the nucleating agent and the thermoplastic polyurethane (P1) or the reaction mixture (R-P1) to obtain a composition (I). The nucleating agent is used here in an amount in the range from 0.01% by weight to 2.0% by weight, based on the thermoplastic polyurethane (P1) or the reaction mixture (R-P1). Further relates the present composition comprising at least one compact thermoplastic polyurethane and at least one compound (N) that has a conjugated, nitrogen-containing aromatic structure as nucleating agent, wherein the compound (N) is a solid, and the use of the compounds mentioned as nucleating agents for a compact thermoplastic polyurethane.

    Abstract: A method of manufacture of zinc monoglycerolate containing an incorporated modifier, and the product, the zinc monoglycerolate being in the form of agglomerates of crystallites, wherein the crystallite size based on the average coherence domain length is not more than 30 nm in the direction, and not more than 60 nm in the direction, as determined by the Scherrer equation via powder X-ray diffraction; and the aspect ratio computed by / coherent domain lengths is less than 0.65, preferably less than 0.56, in particular less than 0.44. Polymers containing this nucleating agent and methods for their production are also described. The zinc monoglycerolate is useful as a nucleating agent, and is very effective at low loading levels in polymers such as polypropylene.
