    • The invention relates to a polyol mixture which comprises as components a1) at least one fat-based polyol, a2) at least one polyetherol having a number average molecular weight of from 500 to 2000 g/mol and a3) if appropriate one or more crosslinkers having a number average molecular weight of from 90 to 400 g/mol, where x) the number average molecular weight of component a1) differs by not more than 400 g/mol from the number average molecular weight of component a2) and xi) components a1) and a2) do not differ from one another in OH functionality by more than 0.5. These polyol mixtures can be employed to produce polyurethane-based embedding compositions. The invention additionally relates to embedding compositions based on the polyol mixtures (A) described at the outset and at least one modified isocyanate (B) and to the use of the embedding compositions as potting material. The invention further relates to a process for producing the embedding compositions as described at the outset. The invention additionally relates to dialysis filters which comprise the embedding compositions described at the outset. Finally, the invention relates to the combination of components (A) and (B) which are present separately but are to be used together.
    • 本发明涉及一种多元醇混合物,其包含作为组分的a1)至少一种基于脂肪的多元醇,a2)至少一种数均分子量为500至2000g / mol的聚乙二醇和a)如果合适的话一种或多种交联剂 数均分子量为90〜400g / mol,其中x)组分a1)的数均分子量与组分a2)和xi)组分的数均分子量不同于400g / mol a1)和a2)在OH官能度上彼此之间的差异不大于0.5。 这些多元醇混合物可用于制备基于聚氨酯的包埋组合物。 本发明另外涉及基于首先描述的多元醇混合物(A)和至少一种改性的异氰酸酯(B)的嵌入组合物以及该嵌入组合物作为灌封材料的用途。 本发明进一步涉及如开始描述的生产嵌入组合物的方法。 本发明还涉及包含首先描述的包埋组合物的透析过滤器。 最后,本发明涉及分开存在但一起使用的组分(A)和(B)的组合。
