Description générale

N,N-Dimethylacrylamide (DMAA) is a non-ionic monomer with high reactivity and low initiation temperature. It is commonly used as a monomer in the production of polymers and copolymers for various applications such as hydrogels, polymeric flocculants, biomedical and drug delivery applications, polymer coatings, smart coatings, adhesives, sensors, self-healing materials, and water treatment agents. The unique structure of DMMA can form a three-dimensional network with other hydrogels and enhance their water retention capacity. It is also used as a crosslinking agent in polymerization reactions.

Application

N, N-Dimethylacrylamide(DMAA) can be used in the following applications:
  • Synthesis of poly(N,N-dimethylacrylamide) (PDMAA) nanoparticles which are used in biomedical and drug delivery applications.
  • Use as a co-monomer in the synthesis of thermoresponsive polymers used in smart coatings, adhesives, and sensors.
  • As a reactive diluent in the manufacture of UV-cured coatings and inks.
  • Use as a co-monomer with polyethylene glycol dimethacrylate (PEGDMA) and a chitosan derivative to develop an injectable hydrogel that can be used as a bone tissue engineering matrix.
  • A series of DMMA-based hydrogels for the removal of heavy metals and organic dyes from polluted water. These hydrogels are highly efficient in removing cationic dyes due to electrostatic interaction and hydrogen bonding in the DMMA backbone.
  • Non-toxic luminescent carbon dot/poly(DMMA) nanocomposite via surface-initiated reversible addition-fragmentation chain transfer polymerization.
  • Polymer coating for quartz crystal microbalance(QCM) sensor. The poly(DMMA) gel acts as a sensing material to adsorb Au(III) ions from HCl aqueous solution and it is inactive to most other metal ions and organic compounds.

Caractéristiques et avantages

  • It is an appropriate precursor for copolymerization due to its low initiation temperature and high reactivity.
  • Its unique structure forms a 3D network and improves the water retention capacity of hydrogels.
  • It is highly soluble in water.
  • It can easily bind to colloidal particles to enhance the bridging effect which plays a key role in flocculation.

Questions

1–3 of 3 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.
      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

  3. I need to know the concentration of product Cat.no.274135-5ML. Thanks

    1 answer

    1. The concentration of this product can be determined using the lot-specific purity reported in the Certificate of Analysis, the density, and the compound's molecular weight. This product has a density of 0.962 g/mL and a molecular weight of 99.13 g/mol. The minimum purity is 98.5%, thus the molarity will vary slightly from lot to lot. The molarity can range from 9.5 M (98.5%) to 9.7 M (100%).

      Molarity = Density x 1000 x Purity / MW
