During the 3rd step, water acted as solvent and piperidine was dripped in at ambient temperature. After reaction at 40 ℃ for 2 h, the mixture was treated with 15%(volume fraction) HCl . The yield was 60.7%. The product has good solubility and photoinitiability. In the air with the distance of 20 cm, the curing time of photosensitive prepolymer was 10s only.展开更多
