一般描述

由于乙烯基的存在和醚的功能性，乙烯基乙醚（又称乙氧基乙烷）反应活性高。 它可以通过不同方法聚合，如自由基聚合、阳离子聚合、氧化聚合，生成乙烯基乙醚或称PVE。它是一种应用广泛的单体，可以合成具有热稳定性和柔韧性的聚合物和嵌段聚合物，用于不同应用，如合成用于隐形眼镜、组织工程、3D打印、药物递送和锂离子电池的硅水凝胶。

应用

乙烯基乙醚可用于：


  • 作为单体合成两性分子嵌段共聚物，从而制备排斥蛋白质的聚合物囊泡（polymersome），生成球形纳米颗粒。这些纳米颗粒可用作药物载体。[1]
  • 作为前体通过紫外光聚合，合成用于固态锂离子电池的聚合物电解质和正极材料。[2]
  • 作为单体通过光诱导自由基促进阳离子可逆加成–断裂链转移（RAFT）聚合，合成具有受控分子量和窄分散性的聚乙烯醚。通过基于立体平版印刷的3D打印，这些聚合物可用于制备具有不同厚度的3D物品。

  • 氢键可重复利用模板辅助对位选择性酮化反应：这项研究讨论了在涉及钯和六氟异丙醇的催化过程中使用乙烯基乙醚来实现酮化反应中的对位选择性，这与用于药物和材料科学中的复杂有机化合物的合成相关（A Maji，A Dahiya，G Lu，T Bhattacharya，2018年）。

  • 光控阳离子聚合的机理研究：探讨了乙烯基乙醚的光控聚合，为光响应材料的开发提供了宝贵的知识，这些材料可能在药物输送和智能材料系统中得到应用（Q Michaudel，T Chauviré，V Kottisch，2017年）。

Questions

1–2 of 2 Questions  

  1. How can I determine the shelf life / expiration / retest date of this product?

    1 answer

    1. If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
      For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
      For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/449/386/product-dating-information-mk.pdf

  2. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer

    1. Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf
