一般描述

甲基丙烯酸酐是一种有机化合物,来源于甲基丙烯酸,属于丙烯酸类。它主要用作聚合物的单体,特别是聚(甲基丙烯酸)及其共聚物的生产中。由于其优异的化学和热稳定性,这些聚合物在广泛的行业中应用,包括生物可再生树脂、pH敏感水凝胶、热固性树脂、涂料、胶粘剂和塑料。在甲基丙烯酸酐的聚合过程中,最常用的抑制剂是Topanol A。通常以小量(2000 ppm)添加,以阻止在聚合过程中不良的副反应,确保受控和高质量的聚合物形成。

应用

甲基丙烯酸酐可用作合成以下材料的起始物:
  • 通过共聚反应合成甲基丙烯酰化软骨素硫酸盐pH敏感水凝胶。这些水凝胶可用于药物传递系统。
  • 高性能木质素基热固性树脂。
  • 凝胶聚合物电解质,然后与阴极集成以形成高性能锂离子电池。
甲基丙烯酸酐也可用作前体,用于合成生物可再生树脂,应用于复合材料应用。例如,它可用于制备大豆油和丁香酚基树脂体系。该树脂具有较高的热稳定性和良好的机械性能,使其成为拉挤工艺的合适基体。

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.

  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
