Methacrylate-Containing Phosphazene Oligomers

Methacrylate-containing phosphazene oligomers are synthesized by the reaction of phosphazene-containing epoxy compounds with methacrylic acid and characterized by 1 Н and 31 Р NMR spectroscopy, MALDI-TOF mass spectrometry, and functional analysis. Methacrylate-containing phosphazene oligomers with the addition of 0.5% hydroquinone are stable under storage at normal temperature for 2 to 3 weeks but are easily involved in benzoyl peroxide-initiated copolymerization with methyl acrylate to give rise to copolymers with the quantitative content of the gel fraction.
