The results show that Irgacure1000 is preferable in the system and the rate is highest when the amount of Irgacure1000 is 3%;the drying condition has a considerable impact on the rate ; it decreases with the increase in neutralization degree;when NaOH is used as neuralization agent,the rate at the later period is higher than that when triethyl amine used; the structure of polymer has a certain effect on the rate and it accelerates with the increase in the ratio of PBA/DMPA and HEAD/DMPA.

结果表明，本体系优选光引发剂Irgacure1000的质量分数为3%时固化速度最快；干燥条件对光固化速度有很大的影响；随着中和度的提高，固化速度下降；用NaOH作为中和剂时，后期固化速度快于用三乙胺；聚合物结构对固化速度有一定的影响，随着PBA/DMPA和HEA/DMPA比例的提高，固化速度加快。

Experimental results showed that the hydrogenation degree can be enhanced significantly by the addition of triphenylphosphine. When the molar ratio of TPP, TPPTS and Ru is 2:5:1, 89% hydrogenation degree can be achieved after 12 h under reaction conditions of 5.0 MPa and 150~C.
