Descrição

Descrição geral

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.

Aplicação

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.

Características e benefícios

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