Abstract: New compounds with carbodiimide units and carboxyl or carboxylate groups are obtained from reaction of : (a) (ar)aliphatic 4-20C polyisocyanates with (b) hydroxycarboxylic acids or their salts and optionally also (c) further compounds giving an addition reaction with NCO groups and/or (d) other isocyanates. The carbodiimide units are derived exclusively from the NCO groups of reactant (a). An independent claim is also included for preparation of the compounds.

Abstract: A polymer film with a microstructured, and where necessary a macrostructured, surface is treated to make it water repellent. It is then attached to the equipment surfaces to be protected. Independent claims are made for: (1) Equipment or equipment components whose surfaces are coated as above; and (2) Use of the coated equipment or components specifically for chemical plant construction.

Abstract: The invention relates to a method for surface-coating apparatuses and parts of apparatuses for the construction of chemical installations, for example apparatus, container and reactor walls, discharging devices, fittings, pumps , filters, compressors, centrifuges, columns, heat exchangers, dryers, reducin g machines, built-in parts, packing and mixing mechanisms. The method is characterised in that bumps with an average height of 100 nm to 50 .mu.m are produced on the surface to be coated, at average intervals of 100 nm to 100 .mu.m, before the surface is coated by currentlessly depositing a layer of metal or a layer of a metal-polymer-dispersion using a galvanisation bath containing a metal electrolyte, a reduction agent and optionally, a polymer or polymer mixture to be deposited, in dispersed form.

Abstract: The invention relates to compounds with carbodiimide units and carboxyl or carboxylate groups (compounds V), which are derived from a) aliphatic or araliphatic C4 to C20 polyisocyanates (component a) b) hydroxycarboxylic aci ds or hydroxycarboxylic acid salts (component b), c) optionally additional compounds which bear groups and which can react with isocyanate groups in an addition reaction (component c) and d) optionally other isocyanates (compone nt d). In the main, the carbodiimide units are derived exclusively from the isocyanate groups of component (a).

Abstract: An aqueous dispersion of a polymer, formed from radically polymerisable compounds (monomers), is characterised in that the dispersed polymer particles contain compounds with carbodimide groups (carbodiimides for short) and that the carbodimides are not covalently bonded to the polymer by means of radical copolymerisation.

Abstract: The invention relates to compounds with carbodiimide units and carboxyl or carboxylate groups (compound V) derived from a) aliphatic or araliphatic C4 to C20 polyisocyanates (component a), b) aminocarboxylic acids or aminocarboxyl ic acid salts (component b), c) optionally further compounds with groups capabl e of reacting with isocyanate groups in an addition reaction (component c) and d) optionally other isocyanates (component d), whereby the carbodiimide unit s are exclusively derived from the isocyanate groups of the components a).
