  Methods for synthesizing isohexide-3,6-dicarbaldehydes and/or isohexide-3,6-dimethanamines from the dehydration products of sugar alcohols (isohexides) and corresponding derivatives are described. The methods involve initially converting the -OH moieties of an isohexide into triflates using triflic anhydride at low temperatures, followed by a carbon-centered nitrile-for-triflate substitution, forming crystalline isohexide-3,6-dinitriles. The isohexide-3,6-dinitriles are then reacted with a reducing agent, such as a metal hydride, in an anhydrous organic solvent at very low temperatures to generate isohexide-3,6-dicarbaldehydes. In a subsequent reductive animation, the isohexide-3,6-dicarbaldehydes are first converted into corresponding diimines, which can be isolated, or then reduced to isohexide-3,6-dimethanamines.

  本文介绍了从糖醇（异己糖）的脱水产物及其衍生物中合成异己糖-3,6-二醛和/或异己糖-3,6-二甲胺的方法。该方法首先使用三氟乙酸酐在低温下将异己糖的-OH官能团转化为三氟甲烷磺酰基，然后进行碳中心的腈-三氟甲烷磺酰基取代反应，形成晶体异己糖-3,6-二腈。然后在无水有机溶剂中，使用金属氢化物等还原剂在极低温度下将异己糖-3,6-二腈还原生成异己糖-3,6-二醛。在随后的还原氨基化反应中，异己糖-3,6-二醛首先被转化为相应的二亚胺，可以被分离出来，或者被进一步还原为异己糖-3,6-二甲胺。

  The present invention refers to a method for producing preferably water-based polymeric compositions, preferably dispersions (i.e. latices), which are particularly useful as or in adhesives, especially pressure-sensitive adhesives (PSAs), particularly pressure-sensitive adhesives removable under neutral or basic (i.e. alkaline) conditions, as well as to the polymeric compositions thus produced and to their various applications, including the copolymers comprised by these polymeric compositions.
