Study on Synthesis and Polymerization of Mono (isopropylmaleate oyloxyl) Diisopropoxyl Dysprosium

Mono(isopropyl maleate oyloxyl) diisopropoxyl dysprosium(DM) was synthesized by the reaction of dysprosium isopropoxide with maleic anhydride. Dy containing polymer(PDM) was obtained by the solution polymerization of DM using 2,2′ azobisisobutyronitrile(AIBN) as an initiator. The kinetic study on the polymerization shows that the polymerization of DM exhibits high apparent activation energy(96 3 kJ·mol -1 ), indicating that the activity of DM is low for polymerization. The kinetic equation of polymerization can be expressed as R p= k p c DM 1.23 c AIBN 0.82 . The polymeric solid material shows excellent heat stability and strong characteristic fluorescence of Dy 3+ , 4F 9/2 → 6H 15/2 and 4 F 9/2 → 6H 13/2 .
