Descrição geral

Maleic anhydride (MA) belongs to the class of monomers known as cyclic dicarboxylic anhydrides. It is commonly used in polymerization reactions to produce various types of polymers such as poly(maleic anhydride) (PMA), maleic anhydride-based resins, and maleic anhydride-butadiene copolymers (MABS), etc. These MA-based polymers find applications in various fields including, polymer blends and coatings, epoxy resins, semiconductor devices, secondary batteries, lithium-ion batteries, resin films, glass fiber, coatings, packaging, water treatment, and drug delivery systems. Additionally, MA can be grafted onto other polymers, to enhance their performance and compatibility with other materials. Grafted polymers find applications in the automotive, packaging, and construction industries. Maleic anhydride is also used as an electron-acceptor monomer in the development of various antimicrobial polymers due to their reactive double bonds and reactive anhydride groups.[1][2][3][4][5]

The structure of maleic acid consists of four carbon molecules along with carboxylate groups on either ends, with a double bond between the central carbon atoms. The anhydride of maleic acid has five atoms in its cyclic molecule, the unsaturated bond undergoes free radical polymerization in the presence of an initiator.

Aplicação

Maleic anhydride can be used as a monomer:
  • In the grafting process of high-density polyethylene (HDPE) by the monomer microencapsulation technique, which enables the introduction of enhanced functionality and improved properties to the polymer for functional coatings, membranes, or surface treatments, adhesives, and coatings.
  • In the functionalization of polylactic acid (PLA) and acts as a coupling agent in natural fiber biocomposites. The functionalization improves the compatibility and interfacial adhesion between PLA and natural fibers, leading to enhanced mechanical properties and expanded applications of the resulting biocomposite materials.
  • Maleic anhydride may be used in the synthesis of unsaturated polyester resins and as a reactant in synthesizing important products such as agricultural chemicals, lubricant additives, and food acidulatents.

Questions

1–4 of 4 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.
      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

  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
