Synthesis and characterization of a new kind of UV-curable Cyclohexanone-Formaldehyde Resins

摘要

A kind of UV-curable cyclohexanone-formaldehyde resins (UVCF) was prepared by the reaction of cyclohexanone-formaldehyde resin (CFR), isophorone diisocyanate (IPDI) and 2-hydroxyethyl acrylate (HEA). The UVCFIPID-HEA obtained was characterized by fourier transform infrared spectrum (FTIR), nuclear magnetic resonance (NMR). The FTIR and ~1H-NMR results show that the terminal acrylate acyloxy was introduced into the structure of the prepolymer. The results of solvent resistance tests show that the solvent resistance property of UVCF_(IPID-HEA) is excellent.
