The invention relates to novel material, forming supramolecular structures below its transition temperature, which contains at least one C=O and/or C=S group and at least one N—H, O—H and/or S—H group and wherein the material has the structure
A(—X—B)
n
(1)
wherein A is a cyclic, aromatic and/or aliphatic group, n being a number of 1 to 4, —X—B is, if n is 2, the same or different, and if n is 3 or 4, the same, partly the same or different and has one of the structures (2) to (4)
NH—C(Y)—Y—B (2)
—NH—C(Y)—NR—B (3)
—Y—C(Y)—NR—B (4)
with Y being an Oxygen and/or Sulfur atom, B being an organic group with at least one heteroatom, where the heteroatom is bound to at least two carbon atoms when B is linear or cyclic, and where the heteroatom is bound to at least one carbon atom when B is branched, and R being a Hydrogen atom, a cyclic, aromatic and/or aliphatic group or another B group which is the same or different. The material can be made by reacting at least one isocyanate and/or thioisocyanate with at least one amine, alcohol and/or thiol. Typically, the material is used first below its transition temperature, followed by increasing the temperature to around or above the transition temperature, carrying out a process step and subsequently decrease the temperature below the transition temperature.
该发明涉及一种新型材料,在其转变温度以下形成超分子结构,其含有至少一个C=O和/或C=S基团,以及至少一个N—H、O—H和/或S—H基团,并且该材料具有结构A(—X—B)n(1),其中A是一个环状、芳香性和/或脂肪族基团,n为1至4的数字,—X—B是,如果n为2,则相同或不同,如果n为3或4,则相同、部分相同或不同,并且具有结构(2)到(4)之一NH—C(Y)—Y—B、—NH—C(Y)—NR—B、—Y—C(Y)—NR—B,其中Y是氧和/或硫原子,B是具有至少一个杂原子的有机基团,当B为线性或环状时,杂原子与至少两个碳原子结合,当B为支链时,杂原子与至少一个碳原子结合,R是氢原子、环状、芳香性和/或脂肪族基团,或另一个相同或不同的B基团。该材料可通过至少一种异氰酸酯和/或硫代异氰酸酯与至少一种胺、醇和/或硫醇反应制备。通常,该材料首先在其转变温度以下使用,随后升高温度至转变温度左右或以上,进行一个工艺步骤,然后降低温度至转变温度以下。
