Rigid polyurethanes are obtained by reacting (1) a polyisocyanate with (2) a polyol mixture made up of

Rigid hydrophobic polyurethanes

Free-flowing compression molding compositions made up of from about 40 to about 80 wt. % of organic filler, from about 20 to about 60 wt. % of an organic reactive resin, and optionally further auxiliary substances and additives. The reactive resin contains an epoxide which may be liquid, a latent catalyst and a powdered polyisocyanate which is solid at room temperature.

The present invention relates to polyisocyanate-modified dicarboxylic acid derivatives obtainable by reacting organic polyisocyanates with excess quantities, based on the equivalent ratio of NCO/COOH groups, of dicarboxylic acid (poly)anhydrides containing free carboxyl groups and water. The present invention also relates to coating compositions, in particular powder coating compositions, containing these polyisocyanate-modified dicarboxylic acids as curing agents for resins containing epoxy groups.

A process for the preparation of a polyurethane-urea elastomer having a mole ratio of NCO groups to all active hydrogen atoms in the range of 0.9 to 1.2 is disclosed. The process comprise reacting (A), (B) and (C.2) for form an NCO-containing prepolymer and then reacting said prepolymer with (C.1) and (D). Accordingly (A) is 5-isocyanato-1-(isocyanatomethyl)-1,1,3-trimethylcyclohexane or bis-(4-isocyanatocyclohexyl)-methane,(B) is polytetrahydrofuran or hexanediol polycarbonate and (C.2) is a chain extender. (C.1) is 5-amino-3-amino-methyl-1,3,3-trimethylcyclohexane or bis-(4-aminocyclohexyl)-methane and (D) is a molecular weight regulator. The elastomer thus produced is particularly suitable for the preparation of moldings, films, flexible tubing (for medical purposes) and catheters.

Cycloaliphatic thermoplastic polyurethane elastomers

The use of dispersions of urea group-containing polyurethanes based on selected starting materials and crosslinkers leads to the production of fully biodegradable shaped bodies.

Biodegradable and compostable shaped bodies

A process for the preparation of thermoplastic polyurethaneurea elastomers is disclosed. Accordingly, organic polyisocyanates (A) and a mixture (B) containing Zerewitinoff active hydrogen atoms, are reacted to yield an intermediate product. The intermediate product is then chain extended by thermal decomposition. Reactant (B) contains
