Abstract: A composition comprising a carbodiimide and a polymer, wherein the carbodiimide comprises a reaction product of a) at least one of an aliphatic C4 to C20 polyisocyanate and an araliphatic C4 to C20 polyisocyanate, b) at least one of a hydroxy carboxylic acid and a hydroxy carboxylic salt, c) optionally, a further compound carrying groups able to react with isocyanate groups in an addition reaction, d) optionally, at least one other isocyanate, and the carbodiimide units being derived essentially exclusively from the isocyanate groups of component a), and the polymer comprises a reaction product of an ethylenically unsaturated carboxylic acid and at least one of a (meth)acrylate, a vinyl ester of a carboxylic acid, a vinyl aromatic compound, an ethylenically unsaturated nitrile, a vinyl halide, an aliphatic hydrocarbon, and a free-radically polymerizable monomer. Also, a method of applying the composition on and/or in a substrate.

Abstract: A polymer material comprising a polyol and at least one alkaline salt. The polyol comprises at least one moiety selected from the group consisting of ethylene glycol, di(ethylene glycol), tri(ethylene glycol), tetra(ethylene glycol), poly(diethylene glycol), poly(ethylene oxide), and mixtures thereof.

Abstract: Polyamides useful as hotmelt adhesives and having improved resistance to hydrocarbons such as gasoline are obtained by reacting a) an acid component containing at least one C6 to C22 aliphatic dicarboxylic acid and b) an amine component containing at least one straight chain alkylene diamine having from 2 to 8 carbon atoms and at least one heterocyclic secondary diamine. The amine component may optionally also contain at least one branched chain alkylene diamine having from 3 to 10 carbon atoms and/or at least one C24 to C48 dimer amine.

Abstract: The reaction of dimer acids, C6 to C18 aliphatic dicarboxylic acids, dimer amines, alkylene diamines having from 2 to 8 carbon atoms, and polyoxyalkylene diamines provides polyamides having excellent cold flexibility, high heat resistance, and low moisture absorbency (low water vapor transmission).
