    • 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.
    • 一种聚醚压印材料,其包含组分(a)聚醚,其具有至少两个任选取代的乙烯基和/或烯丙基端基,(b)SiH组分,(c)铂催化剂和任选地(d) 通常的添加剂,其特征在于SiH组分(b)可以通过至少二官能或多官能的,例如三官能的烯丙基或乙烯基烃化合物,其烃基,而不考虑 的烯丙基或乙烯基和任选存在的亚烷基醚基具有6至30个C原子并且含有至少一个芳族不饱和的,杂环的或脂环族的环,每个乙烯基或烯丙基具有至少一个摩尔 至少一种双官能或多官能的例如三官能的下式的化合物:其中e = 0至8,g = 0至8,h = 0至4,R4和R10为 相同或不同,并且各自为H,甲基或乙基,条件是R 4的至少1和最多5个 至R 10为H,其中g和h不能同时为O,并且其中至少组分(b)和(c)在空间上彼此分离。
