    摘要： A polyether-impression material comprising components(a) a polyether, which has at least two optionally substituted vinyl- and/or allyl-end groups,(b) an SiH component,(c) a platinum catalyst, and optionally(d) the usual additivescharacterized in that the SiH-component (b) can be obtained by the reaction of at least a bi- functional, or polyfunctional, e.g., trifunctional, allyl- or vinyl-hydrocarbon compound, the hydrocarbon radical of which, without taking account of the allyl- or vinyl-groups and the optionally present alkylene ether groups, has 6 to 30 C-atom and contains at least one aromatically unsaturated, heterocyclic, or cycloaliphatic ring, with at least one mole per vinyl- or allyl-group of at least a bifunctional, or polyfunctional, e.g., trifunctional, SiH compound of the formula: ##STR1## in which e=0 to 8,g=0 to 8,h=0 to 4 andR.sup.4 and R.sup.10 are the same or different, and are each H, methyl or ethyl, with the proviso that at least 1 and at the most 5 of R.sup.4 to R.sup.10 are H, wherein g and h cannot simultaneously be O, and wherein at least the components (b) and (c) lie spatially separated from each other.

    摘要： There is disclosed a polyether impression material containing(a) a polyether,(b) a catalyst, and(c) a mixing additive,in which the components (a) and (b) are spatially separate from each other, and in which the mixing additive (c) is polyalkylene oxide derivative with a molecular weight above 300, which is chemically inert with the other components present and in particular, does not contain hydroxyl groups, acid groups, primary amino groups, ionic groups, halogen groups or groups capable of polymerization. The composition can be mixed easily, has outstanding storage stability and does not dissociate even under increased pressure.
