Abstract

221 type alicyclic epoxy resin was cured by UV-light initiated descending frontal polymerization. The effect of amount of photo/thermal initiator, pre-heating temperature on the frontal velocity Vf and frontal initiating time ti was investigated. The structure and thermal properties of the cured products were characterized via Fourier transform infrared spectroscopy(FTIR), thermogravimetric analysis(TG) and differential scanning calorimetry(DSC). The results show that frontal velocity Vf increase with increasing of concentration of photo/thermal initiator or preheating temperature, while frontal initiating time decrease. Analysis of the FTIR spectrum indicates that the products were obtained uniformly. TG and DSC results reveal that the products exhibit good thermal stability.
