Description générale

Bis[2-(methacryloyloxy)ethyl] phosphate (BMEP) is a hydrophilic monomer with two polymerizable methacrylate groups and a centrally placed phosphate group. In presence of an acid, it can undergo spontaneous polymerization with a high degree of conversion. It is widely used as a precursor in the synthesis of poly (BMEP), dental resins, hydrogels, and fire-retardant polymer composites.

Application

Bis[2-(methacryloyloxy)ethyl] phosphate (BMEP) can be used:
  • As a bifunctional crosslinker to synthesize superabsorbent polymers (SAPs) via free radical polymerization. These SAPs can be used for agricultural applications.
  • To prepare self-etching primer formulations for enamel and dentine. Primers with BMEP exhibit good wetting, etching, and penetration in both dentine and enamel.
  • As a precursor to synthesize fire retardant nanocomposites via suspension polymerization.

Caractéristiques et avantages

  • Presence of dimethacrylate groups enables cross-linking and improves copolymerization.
  • Hydrophilicity and short carbon chains can enhance wetting.

Sorption mechanism of uranyl by poly(bis[2-(methacryloyloxy)ethyl] phosphate) (PB2MP) functionalised polyvinylidene fluoride (PVDF) track-etched membranes, PB2MP-g-PVDF, was investigated. It was found that uranyl sorption obeyed Langmuir isotherm model giving a maximum U(VI) membrane uptake of 6.73 μmol g-1 and an affinity

The development of adsorbents with high adsorption capacity and fast separation is of utmost importance for the environmental management of dye-bearing wastewaters. Within this scope, crosslinked hydrogels including poly(vinylphosphonic acid) (PVPA) and bis[2-(methacryloyloxy)ethyl] phosphate (BMEP) were designed with varying mole

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.
