Allgemeine Beschreibung

Poly(maleic anhydride-alt-1-octadecene) is a non-polar polymer.[1]

Anwendung

Release coatings, anti-corrosive, thickening agent, chelant/surfactant and cross-linker for epoxy or alcohol functional polymers.
Poly(maleic anhydride-alt-1-octadecene) (PMHC18) may be used to water-solubilize nanoparticles.[2] PMHC18 may be used to improve the pour point (PP) properties of palm oil methyl esters for its application as a vegetable oil-based biodiesel.[1] In vivo behaviors of single-walled nanotubes (SWNTs) can be fine tuned by coating SWNTs with polyethylene glycol (PEG) grafted PMHC18 polymers.[3]

Leistungsmerkmale und Vorteile

Readily derivatized to acid salt, amide, ester or imide. Alternating polymer.

Questions

1–2 of 2 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.
