Production of cellular plastics by the polyisocyanate polyaddition

Novel esters containing bonded fluorocarbon and oxypropylenealkylether groups and of the formula ##STR1## where Rf is straight-chain or branched, partially fluorinated or perfluorinated alkyl of 2 to 10 carbon atoms, partially fluorinated or perfluorinated cycloalkyl of 4 to 8 carbon atoms,

Esters containing bonded fluorocarbon and oxypropylenealkylether groups,

Emulsifier-free aqueous polyurethane dispersions are prepared by reacting (a) dihydroxy compounds, (b) diisocyanates and (c) chain extenders to give a prepolymer having terminal isocyanate groups, then reacting the prepolymer with (d) salts of aliphatic aminocarboxylic or -sulfonic acids or amino-containing or hydroxyl-containing tertiary ammonium salts, dispersing the resulting polyurethane in water and, if required, removing the organic solvent by distillation. In the process, an organic condensation resin which is dissolved in a solvent is admixed before the polyurethane obtained is dispersed in water.

Process for producing cellular plastics by the polyisocyanate

A cellular polyurethane having a density of from 15 Kg/m.sup.3 to 400 Kg/m.sup.3 obtained by means of thermoforming, in a forming tool, at a compression factor of from 1 to 10 and temperatures of from 140.degree. C. to 200.degree. C., polyester-urethane foams having a density of from 15 Kg/m.sup.3 to 40 Kg/m.sup.3 which are based on aromatic polyisocyanates and polyester polyols. The resulting polyurethane shaped objects are suitable for use as self-supporting trim panels, headliners, engine compartment covers, or instrument panels in the automotive, aircraft or railway industries.
