| Zusammenfassung: | The present invention relates to polyurethane cast elastomers based on 2,3,5,6-tetramethyl-1,4-diisocyanatobenzene (also known as "durene diisocyanate"), their preparation and their use for the production of moldings exposed to high mechanical stresses.
The present invention relates to polyurethane cast elastomers which are prepared from higher molecular weight polyhydroxy compounds, durene diisocyanate and low molecular weight chain-lengthening and/or crosslinking agents. These elastomers are particularly useful for the production of moldings exposed to high mechanical stresses. |
