摘要：

The vinyl group containing polymer was synthesized via radical polymerization of acrylic monomers followed by reaction with methacrylic oxyethyl isocyanate(MOI). Stable dispersions of the vinyl group containing polymer, pentaerythritol triacrylate(PETA) and photo initiator were prepared by neutralization of the above synthesized polymer with lactic acid. Electro-deposition process was introduced to apply UV-curable acrylic dispersion into the nickel-plated plastic substrate. The prepared dispersion containing PETA has higher particle size and higher deposition yield than those of the dispersion without PETA. The electro-deposited film was cross-linked by UV radiation after 10 minutes flash-off stage at 80degreesC. The kinetic study by real-time FT-IR revealed that the cross-linked films containing PETA gave higher conversion than those without PETA resulting in harder film.
