  天然和全甲基化的含亚烷基桥基的基于α-环糊精的轮烷的结构分析和包合机理

  摘要：

  天然α-环糊精（α-CD）和全甲基化α-CD（PMeCD）的轮烷具有各种亚烷基短链作为轴，可以通过尿素封端法合成。天然α-CD倾向于形成[3]-或[5]假轮烷，而不是[2]-或[4]假轮烷，这表明偶联的CD充当单个片段。轴长为C18和C24的假轮烷的封端反应不会发生，因为轴末端被密集堆叠的CD覆盖。假轮烷上的PMeCD的数量是灵活的，并且主要取决于轴长。基于过乙酰化的α-CD（PAcCD）的轮烷是通过基于α-CD的轮烷的O-乙酰化而合成的，而轮烷的结构没有任何分解。基于PMeCD的[3]和[4]轮烷的结构，以及[3]假轮烷的分子动力学计算，表示PMeCD的尾面有规律地指向轮轴总站。根据获得的结果，可以得出结论，含有短亚烷基链的轮烷中CD的方向和数量取决于1）CD之间的相互作用，2）亚烷基轴的长度以及3）烷基之间的相互作用。 CD的轴端和尾端。

  Disclosed herein is a one-component sealant compound being based on a silicone-modified polyether polymer having methyl dimethoxysilyl functional groups on ends of a polyproylene oxide main chain, which is blended with a plasticizer, a filler, an adhesive additive agent and a curing catalyst, as well as a meta/acrylic component prepared by dissolving a copolymer of two or three of ethyl acrylate, propyl acrylate, butyl acrylate, methyl methacrylate, butyl methacrylate and lauryl methacrylate in a solvent and an amine component prepared by dissolving a solid long-chain primary or secondary saturated monoamine or diamine having a melting point in a range of 40 to 100°C in a solvent. The meta/acrylic component and the amine component migrate to the surface of the sealant in a curing process at a higher speed than the plasticizer to form a barrier film layer on the surface, thereby preventing the same from surface pollution.
