    摘要: The invention relates to impression compositions based on vulcanizable pother materials, which are characterized in that the ready-mixed pastes comprisea) approx. 30 to 70 wt. % of aziridino-polyether,b) approx. 5 to 20 wt. % of a triacyl glyceride of non-animal origin which has a stearoyl content of .gtoreq.70 wt. %, based on the acyl content of the triacyl glyceride, or, in the case of a lower stearoyl content and if this adversely influences the storage stability of the impression composition, has been esterified in itself beforehand, andc) approx. 10 to 65 wt. % of customary catalysts, auxiliaries and additives,in each case based on the total weight of the composition.The impression compositions are distinguished by consistently good mechanical properties of the polymerized materials, have a comparatively low proportion of aziridino-polyether, which has a favourable effect on their preparation costs, and can easily be mixed. During storage of the compositions over long periods of time, no noticeable increase in viscosity occurs, even at elevated temperatures.
