新型高分子亚砜树脂的合成及表征方法研究

Research of Synthesis and Structure Characterisation on Macromolecule Sulphoxide Resin

实验将交联氯甲基化聚苯乙烯树脂进行改性,与巯基化合物反应合成一种新型高分子亚砜树脂,用FT-IR光谱法、NMR核磁共振碳谱、XPS能谱等方法表征了该化合物的结构组成。分析表明,该方法可以成功地对氯甲基聚苯乙烯树脂进行接枝改性,使其具备亚砜化合物的性质,可以利用亚砜与贵金属络合的反应机理对贵金属分离富集。

The experiments research of the reaction between the chloromethyl polystyrene and thiol compounds, and synthesize a kind of sulfoxide macromolecule resin. Its structure, elements and extraction mechanism were analyzed by FT-IR, NMR spectrum and X-ray photoelectron spectrum. The experiment indicated that the synthesis method could be applied in the character modification of the compounds, and make it have a characteristic of sulfoxide compounds of metal extraction.
