    Abstract: PROBLEM TO BE SOLVED: To obtain a low-fogging catalyst not migrating from a polyurethane, not causing any trouble in polyurethane production, being simply synthesized by reacting a polymer compound containing a carboxyl group and/or a carboxylic acid anhydride, etc., with a specific compound. SOLUTION: This catalyst is synthesized by reacting (A) a polymer compound containing a carboxyl group and/or a carboxylic acid anhydride with (B) a monocarboxylic acid compound and a dicarboxylic acid compound containing at least one primary or secondary amino group and/or (C) a compound containing at least one tertiary amino group, at least one carboxyl group and a group to be reacted with the carboxylic acid anhydride. Preferably the component A is a homopolymer or a copolymer of an olefinic unsaturated monocarboxylic acid and a dicarboxylic acid and/or a copolymer of an olefinic unsaturated monocarboxylic acid, a dicarboxylic acid and a 2-40C olefin.

    Abstract: PROBLEM TO BE SOLVED: To obtain the subject polyurethane by using a means capable of performing a thermoplastic processing without a troublesome chemical treatment by adding a crushed state of crosslinked polyurethane to a reaction product mixture. SOLUTION: A thermoplastic polyurethane is produced by reacting isocyanate with a compound reactive with the isocyanate in the presence or absence of a chain extender, a catalyst and a usual auxiliary and an additive. In the process, crosslinked polyurethane in crushed shape is added to the reaction mixture before, during and/or after the reaction. Preferably, a dimension of the crushed crosslinked polyurethane is within the range of 0.1-25mm and a weight ratio of the crushed polyurethane to the reaction mixture is (0.001:1)-(4:1), and an equivalent ratio of the isocyanate group to total or the reactive hydrogen atom is (0.9:1)-(1.5:1).
