    Abstract: Latent hardening aqueous polyurethane dispersions contain (1) a disperse phase (P.1) containing (1a) a polyurethane (PUR.1a) containing groups (G-1) imparting dispersibility in water and groups (G-2) with a carbon-carbon (C-C) double bond activated by a carbonyl group bound directly to this or (1b) a mixture of a polyurethane (PUR.1b) containing G-1 groups but not G-2 groups and a compound (I) containing G-2 groups, other than PUR.1a and PUR.1b; and (2) a compound (II) which contains an average of NOTLESS 2 hydrogen (H) atoms as amino function, has a water solubility > 1 g/l (25 degrees C) and has a number average molecular weight (Mn) of 200-1000000. Also claimed are wood, metal, textile, leather or plastics articles bonded, impregnated or coated with the dispersions.

    Abstract: Carbodiimides which are solid at 25 degrees C, containing carbodiimide structures which are attached to non-aromatic carbon atoms, together with urethane and/or urea structures. Independent claims are also included for: (a) a process for the production of these solid carbodiimides from di-isocyanates in which the isocyanate (NCO) groups are not attached to aromatic carbon, by reaction in presence of catalysts to form the carbodiimide with cleavage of carbon dioxide, followed by reaction with compounds containing at least two NCO-reactive groups; (b) another process in which the above stages are reversed and the ratio of NCO groups to NCO-reactive groups used in the first stage is at least 2:1; (c) solid carbodiimides obtained by these processes; (d) mixtures containing compounds with ester units together with these carbodiimides; and (e) mixtures containing these carbodiimides and at least one of the following: polyurethanes with ester units and/or polycondensation products such as polyesters, e.g. polyethylene- or polybutylene- terephthalate, polyether-esters, polyester-esters, polyester-amides, polycaprolactones, unsaturated polyester resins and polyamides.

    Abstract: Aqueous dispersions (AD) containing a polyurethane (PU) derived from (a) 4-30C di-isocyanates, (b) diol(s), of which (b1) 10-100 mole% have a mol. wt. of 500-5000 and are derived from (b1.1) (4-30C alkyl and/or alkenyl)-succinic acid, (b1.2) 0-60 mole% (based on b1.1) of another dicarboxylic acid and (b1.3) a diol with a mol. wt. of 60-500, (b2) 0-90 mole% have a mol. wt. of 60-500 and (b3) 0-90 mole% are diol(s) other than (b1.1) with a mol. wt. of 500-5000, (c) monomers other than (a) and (b) with two isocyanate (NCO) groups or two NCO-reactive groups and also one hydrophilic or potentially hydrophilic group to confer water-dispersibility on the PU, (d) optionally multifunctional compounds other than (a)-(c) with reactive alcoholic hydroxyl, primary or secondary amino, or NCO groups, and (e) optionally mono-functional compounds other than (a)-(c) with one reactive group as in (d). Also claimed are articles of leather, paper, textiles, plastics or metal, coated or adhesively bonded with (AD).
