General description

Acrylic acid is an unsaturated carboxylic acid that is commonly used as a versatile building block in the chemical industry because of its reactive double bond between the carbon and oxygen atoms. It is used to prepare various acrylic acid-based polymers, which are used for various applications such as adhesives, paints & coatings, medical devices, organic semiconductors,thin-film transistors, hydrogels and lithium-ion batteries. Additionally, acrylic acid also serves as one of the polyelectrolytes in the self-assembled polymeric film used for hydrogen generation.[1][2][3]

Application

Acrylic acid can be primarily used as a monomer to produce various acrylic polymers, including polyacrylic acid, polymethyl methacrylate (PMMA), acrylonitrile butadiene styrene (ABS), and many others. These polymers exhibit a wide range of properties, such as transparency, scratch-resistant, flexibility, and resistance to water and chemicals, which make them valuable materials in various applications. Acrylic acid is also used as a key component in the synthesis of superabsorbent polymers(SAPs). These polymers possess a unique ability to quickly absorb and retain large quantities of water. Due to their excellent properties, SAPs have been widely used in many fields, such as drug-delivery systems, chemical industry, and personal care, etc.

Acrylic acid can also be used as:
  • A key component in the preparation of copolymer binder, which helps to optimize the performance of lithium-ion batteries.
  • A surface modifier for the carbon nanotubes with poly(acrylic acid) in order to improve adhesion and dispersion of the nanotubes in the oxide semiconductor matrix for thin-film transistor applications.
  • A reactive monomer for the surface modification of polydimethylsiloxane (PDMS)through a simultaneous polymerization process with ethylene glycol dimethacrylate. Modified PDMS potentially applied in new applications fields such as microfluidics or biomedical devices.
  • A precursor for the synthesis of cashew gum/acrylic acid nanoparticles via the copolymerization process. The use of acrylic acid in the synthesis is to introduce hydrophilic functional groups into the cashew gum backbone, thereby improving its solubility in water and increasing its compatibility with other hydrophilic materials.
AAc is used in preparing monodispersed poly (N-isopropylacryamide) (PNIPAM)/AAc microgels. AAc has been plasma-deposited on surfaces for cell culture applications.[4] Surface modification of poly(ethylene terephthalate) (PET) films via UV-induced graft copolymerization with AAc has been reported.[2] AAc is used primarily as an intermediate in the production of acrylates.

Questions

1–8 of 8 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/418/501/product-dating-information-06-25-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
