超交联聚合物的合成及其对碘吸附性能的研究

Synthesis of Hyper Crosslinked Polymers and Their Adsorption Properties for Iodine

本文以苯为原料,采用二氯乙烷(DCE)为溶剂、二甲氧基甲烷(FDA)为交联剂、无水三氯化铁为催化剂合成了一系列超交联聚合物(HCP1-5)。探讨了单体、交联剂和催化剂的比例对碘吸附量的影响。实验结果表明:改变原料比例可以调节孔道性能,进而调控碘吸附量;当单体、交联剂和催化剂的比例为1:3:3时,碘吸附量可高达2.2 g/g,储存稳定性达90.6%。

In this paper,a series of hyper crosslinked polymers(HCP1-5)were synthesized from benzene,dichloroethane(DCE)as solvent,Dimethoxymethane(FDA)as crosslinking agent and anhydrous ferric chloride as catalyst.The effects of the ratio of monomer,crosslinker and catalyst on iodine adsorption were discussed.The experimental results show that changing the proportion of raw materials can regulate the pore properties and then the iodine adsorption capacity.When the ratio of monomer,crosslinking agent and catalyst is 1:3:3,the iodine adsorption capacity can be as high as 2.2 g/g and the storage stability can reach 90.6%.
