    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 comprising a polyurethane synthesized from a) diisocyanates, b) diols of which b 1 ) from 10 to 100 mol %, based on the total amount of diols (b), have a molecular weight of from 500 to 5 000, and b 2 ) from 0 to 90 mol %, based on the total amount of diols (b), have a molecular weight of from 60 to 500 g/mol, c) monomers other than the monomers (a) and (b), containing at least one isocyanate group or at least one isocyanate-reactive group and further carrying at least one hydrophilic group or potentially hydrophilic group by means of which the polyurethane is made dispersible in water, d) if appropriate, further, polyfunctional compounds other than the monomers (a) to (c), containing reactive groups which are alcoholic hydroxyl groups, primary or secondary amino groups or isocyanate groups, and e) if appropriate, monofunctional compounds other than the monomers (a) to (d), containing a reactive group which is an alcoholic hydroxyl group, a primary or secondary amino group or an isocyanate group, wherein the diols b 1 comprise less than 0.5 part by weight of cyclic compounds per 100 parts by weight of diols b1.

    Abstract: A process for adhesively bonding a substrate, using an adhesive comprising a polymer binder and a crosslinker compound I comprising carbodiimide groups, wherein the compound comprising carbodiimide groups is obtainable by reacting a) carbodiimides of 1,3-bis(1-methyl-1-isocyanatoethyl)benzene, 1,4-bis(1-methyl-1-isocyanatoethyl)benzene or a mixture thereof with b) polyalkylene oxides having at least two isocyanate-reactive groups, preferably at least two hydroxyl groups, and c) if appropriate, further compounds reactive with a) or b).
