The suitabale ratio material and reaction conditions were selected, saturated acid such as m-phthalic acid, o-phthalic acid and their mixing acid(m/o-phthalic acid mol ratio 4:1), mix disalcohol(propanediol/diethylene glycol mol ratio 4:1) were used, respectively. Three kinds of resins(they are m-UPR, o-UPR and mix-UPR, respectively) have been prepared. They can be cured when 1% mass fraction Benzoin ethyl ether is added in the resins, and UV illumination for 30 min. In cured resins, the property of m-UPR is the best in acid-restant, base-restant, dissolvent-restant and surface luster of the UV-cured resins. Their UV-curing process has been investigated by FTIR spectra. The hermostability of the cured resins are studied by TG/DTA technique, it is found that loss gravity of o-UPR begins at 100℃ but m-UPR do not happen at 300℃. In addition, UV-cured resins have better themostability than resins cured by peroxide.
