Multi-hydroxymethyl-phenol acrylate which is suitable for waterborne UV curing coating was synthesized by using multi-hydroxymethyl phenol sodium and acryloyl chloride as raw material. Chemical structure of the product was characterized by FT-IR. The relation between the production yield and material ratio, reaction temperature, reaction time and catalyst content was discussed. The results showed that the most favorable reaction condition is when n(multihydroxymethyl phenol sodium)∶n(acryloyl chloride)=1∶2, reaction temperature at 0~- 5℃, reaction time 2.5 h, the content of tetrabutyl ammonium bromide 0.04%(accounting for materials quality ratio); water-soluble and film properties of the multi-hydroxymethyl-phenol acrylate can satisfy the application of waterborne UV curing coating.
