Descrição geral

Ethyl vinyl ether, also known as ethoxy ethane is highly reactive due to the presence of the vinyl group and the ether functionality. It can polymerize via different methods like radical polymerization, cationic polymerization, oroxidative polymerization, yielding poly(ethyl vinyl ether) or PVE. It is widely used as a monomer to synthesize copolymers and block polymers with thermal stability and flexibility for various applications such as the synthesis of silicone hydrogel for contact lenses, tissue engineering, 3D bioprinting, drug delivery, and Li-ion batteries.

Aplicação

Ethyl vinyl ether can be used as:


  • A monomer to synthesize amphiphilic block copolymers to fabricate protein-repelling polymersomes to produce spherical nanoparticles. These nanoparticles can be used as drug carriers.[1]
  • A precursor to synthesize polymer electrolytes and cathode materials for solid-state lithium-ion batteries via UV photopolymerizations.[2]
  • A monomer to synthesize poly(vinyl ether)s with controlled molecular weight and narrow dispersity via photoinduced free radical-promoted cationic reversible addition–fragmentation chain transfer (RAFT) polymerization. These polymers are used to fabricate 3D objects with different thicknesses by employing stereolithography-based 3D printing.

  • H-bonded Reusable Template Assisted para-Selective Ketonisation: This study discusses the use of ethyl vinyl ether in catalytic processes involving palladium and hexafluoroisopropanol to achieve para-selectivity in ketonisation, relevant for synthesizing complex organic compounds used in pharmaceuticals and materials science (A Maji, A Dahiya, G Lu, T Bhattacharya, 2018).

  • Mechanistic Insight into Photocontrolled Cationic Polymerization: Explores the photocontrolled polymerization of ethyl vinyl ether, providing valuable knowledge for the development of light-responsive materials, which could have applications in drug delivery and smart material systems (Q Michaudel, T Chauviré, V Kottisch, 2017).

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
