General description

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.

Features and Benefits

  • 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
