利用环氧化苯乙烯-丁二烯-苯乙烯嵌段共聚物(SBS)的环氧基与顺丁烯二酸氢钾在相转移催化剂及二甲基苯胺存在下开环反应制得钾离聚体。研究了其反应条件,得到了环氧基的最大转化率达 65%,并用红外光谱确定其为离聚体。
The use of epoxidized styrene - butadiene - styrene block copolymer (SBS) of the epoxy group and potassium maleate in the presence of phase transfer catalyst and dimethylaniline ring-opening reaction in the presence of potassium Polymer. The reaction conditions were studied. The maximum conversion of epoxy groups was 65%, and it was confirmed by infrared spectroscopy as ionomer.
