Descrição geral

O dimetilacrilato de etilenoglicol (EGDMA) é um diéster formado por condensação de dois equivalentes de ácido metacrílico e um equivalente de etilenoglicol.

Aplicação

O dimetacrilato de etilenoglicol pode ser usado como um reticulante napreparação de:

  • um sistema de terpolímero, poli(acrilonitrila-co-etilenoglicoldimetacrilato-co-cloreto de vinilbenzil), que é aplicável como um sorventena adsorção de produtos farmacêuticos.
  • Hidrogel à base de PVA (álcool polivinílico) por copolimerizaçãode radical livre. Essas redes de polímeros PVA podem ser usadas como sistemas de distribuiçãode medicamentos.
Também podem ser usadas comocomo monômero na preparação de microesferas de copolímero de poli(etilenoglicol dimetacrilato/ácido acrílico) incháveis e não incháveis por meio de polimerizaçãoem suspensão.

The cytotoxicity of 2D graphene-based nanomaterials (GBNs) is highly important for engineered applications and environmental health. However, the isotropic orientation of GBNs, most notably graphene oxide (GO), in previous experimental studies obscured the interpretation of cytotoxic contributions of nanosheet edges.

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
