摘要： The invention relates to a method for producing polyester polyols having secondary hydroxyl terminal groups, comprising the step of reacting polyester comprising carboxyl terminal groups with an epoxide of the general formula (1), where R1 stands for an alkyl radical or an aryl radical, and the reaction is performed in the presence of a catalyst comprising at least one nitrogen atom per molecule. The method is characterized in that the polyester comprising carboxyl terminal groups has an acid number of = 25 mg KOH/g to = 400 mg KOH/g and a hydroxyl number of = 5 mg KOH/g, and that the polyester comprising carboxyl terminal groups is produced in that = 1.03 mol to = 1.90 mol of carboxyl groups or carboxyl group equivalents of an acid component are added per mol of hydroxyl groups of an alcohol. The polyester polyols comprising secondary hydroxyl terminal groups thus obtained can be used for producing polyurethane polymers.

摘要： Stable NCO prepolymers are produced from polyisocyanates having a melting point greater than 70°C, preferably, naphthalene diisocyanate, having advantageous physical properties. An important feature of the process of the present invention is the rapid cooling of the prepolymer. The process of the present invention may be carried out on a continuous or batch basis. The prepolymers of the present invention are particularly suitable for the production of cast polyurethane elastomers.

摘要： New polyester polyols (I), of functionality 1.95-3.25 and hydroxyl index 90-33 mg KOH/g, are obtained by (a) reacting 4-12C polycarboxylic acids (II) with polyols (III) to give hydroxy-terminated polyester polyols (IV) of hydroxyl index 100-40 mg KOH/g and functionality 1.95-3.25; and (b) adding cyclic ester monomers (V) at (IV) to (V) weight ratio 1-10:1, such that the hydroxyl index of (IV) is reduced by at least 5 mg KOH/g. Preparation of polyester polyols (I), of functionality 1.95-3.25 and hydroxyl index 90-33 mg KOH/g, involves: (a) reacting 4-12C di-, tri- and/or tetracarboxylic acid(s) (II) (or their derivatives) with polyols (III), of functionality 2-4 and number average molecular weight 62-400, at 150-250[deg] C under vacuum to give hydroxy-terminated polyester polyols (IV) of hydroxyl index 100-40 mg KOH/g and functionality 1.95-3.25; and (b) adding cyclic ester monomers (V) at (IV) to (V) weight ratio 1-10:1 and an initial temperature below 220[deg] C, such that the temperature is at 175[deg] C or less after at most 60 minutes and the hydroxyl index of (IV) is reduced by at least 5 mg KOH/g. The molar ratio of (V) to the hydroxy groups of (IV) is 0.75-10:1. An independent claim is included for the polyester polyols (I) as new compounds, where (I) are obtained by reacting (IV) (obtained from (II) and (III)) with (V) as described above (except that the temperature and pressure conditions are not specified).
