Abstract

The synthetic method of UV-curable polyacrylic acid resin was introduced.The effects of dodecyl mercaptan and methylphenylethylene linear dimer on the viscosity,appearance,molecular weight,molecular weight distribution and film properties of the resin were discussed.The results showed that methylphenylene linear dimer was more suitable for the synthesis of light curing polyacrylic acid resin.

Key words

chain transfer agent;UV curing;polyacrylic resin;relative molecular mass
