    • 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.
    • 本发明涉及基于可硫化聚醚材料的印模组合物,其特征在于,预混合浆料包括a) 30〜70重量% %的氮丙啶基 - 聚醚,b) 5〜20重量% %的非动物来源的甘油三酯的硬脂酰含量≥70重量%。 %,基于三酰基甘油酯的酰基含量,或在低硬脂酰基含量的情况下,如果这不利地影响印模组合物的储存稳定性,其本身已被酯化,并且c)约。 10〜65重量% %的常规催化剂,助剂和添加剂,在每种情况下,基于组合物的总重量。 印模组合物通过聚合材料的一贯良好的机械性能来区分,具有相对低比例的氮丙啶基 - 聚醚,其对其制备成本具有有利的影响,并且可以容易地混合。 在组合物长时间储存​​期间,即使在升高的温度下也不会出现明显的粘度增加。
