Allgemeine Beschreibung

Methyl acrylate is an acrylic monomer. It is useful in the preparation of polymers having rigid, flexible, ionic, nonionic, hydrophobic, or hydrophilic properties. Mechanism of the copolymerization of ethylene and α-olefins with methyl acrylate has been studied.[1] Heck reaction of iodobenzene with methyl acrylate in the presence of triethylamine and sodium carbonate has been reported.[2] The reversible addition fragmentation chain transfer (RAFT) bulk polymerization of methyl acrylate using 1-phenylethyl dithiobenzoate and 2-(2-cyanopropyl) dithiobenzoate (RAFT agents) has been studied.[3] Reactive intermediates formed during the Heck reaction of methyl acrylate have been characterized by NMR spectroscopy.[4]

Anwendung

Methyl acrylate was used in the preparation of poly(methyl acrylate) elastomers.[5] It was also used in the synthesis of α,ω-dicarboxylic acid esters.[6]

Our strategy is to synthesize mesoporous carbonaceous materials (“Starbons”) using mesoporous expanded starch as the precursor without the need for a templating agent.

RAFT polymerization offers living characteristics to radical polymerization, contributing versatility to reversible deactivation radical polymerization methods.

Fragen

1-2 von 2 Fragen  
  1. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 Antwort
    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 Antwort
    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.
