一般描述

4-乙烯基苄基氯（VBC）是常用的单体，属于芳基氯类，其结构中同时含有乙烯基（CH2=CH-）和苄基氯基团（C6H4CH2Cl）。它在各种聚合反应中用作反应性结构单元，合成不同类型的聚合物，具有优异的热稳定性、耐化学性和良好的成膜性能。它通常用于生产树脂、涂料、粘合剂和离子交换树脂。它在聚合物合成中提供了多功能性，允许将所需的功能引入聚合物中。

还是：
  • 离子交换树脂、光刻胶聚合物、可交联纤维、偶联剂和导电聚合物的组分。
  • 各种共聚物制备的起始剂。
  • 双功能单体。易于通过氯化物置换衍生化。

应用

4-乙烯基苄基氯可以作为单体合成：
  • 用于超级电容器应用的超交联聚合物。4-乙烯基苄基氯的掺入有助于形成多孔结构和比表面积，从而促进有效的电解质离子扩散并为电荷存储提供充足的位点，从而增强电化学性能。
  • 采用基质辅助脉冲激光蒸发（MAPLE）技术制备的聚合物薄膜。所得聚合物薄膜可以表现出非线性光学效应，例如光学二次谐波产生、电光调制或光学频率转换。这些特性使它们适合非线性光学器件中的各种应用。

Ionic liquids (ILs) have been efficiently used as a "designer sorbent" in sample preparation. A novel 1-(3-aminopropyl)-3-(4-vinylbenzyl)imidazolium 4-styrenesulfonate IL monomer was synthesized and copolymerized with 1,6-di(3-vinylimidazolium) hexane bishexafluorophosphate IL as cross-linking agent to prepare a cross-linked polymeric ionic liquids (PILs)

Questions

1–3 of 3 Questions  

  1. 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

  2. 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
