Abstract

In a process for the manufacture of a flexible polyurethane plastic material, a linear aliphatic hydroxy-polyester is reacted with an excess of a di-isocyanate and to the isocyanate polyester obtained there is added 0,001 to 0,1% by weight of an alkali metal salt of a fatty acid, an arylsulphonate or an alkali sulphonate, as activator, and there is also incorporated into the isocyanate polyester at raised temperature a reticulator which comprises a mixture of a dihydric and a trihydric alcohol, the dihydric alcohol in the mixture having been first saturated with pentaerythritol at the raised temperature to such an extent that a sediment of pentaerythritol remained and then filtering off the said sediment. In an example excess 1:5-napththalene diisocyanate is reacted with an adipic acid/ethylene glycol hydroxypolyester containing 0,001% of sodium stearate. There is then added a reticulator mixture comprising butane 1:4 diol and trimethylol propane which has been saturated at 110 DEG C. with pentaerythritol, and the reaction mixture is maintained at 110 DEG C. The products are useful as inserts for the disc wheels of rail cars such as those described in Specification 791,371.
