Abstract
A new kind of sulfonate-containing polyether organosilicone (SPES) was synthesized by the sulfonation reaction of epoxy group polyether organosilicone (EPES) with potassium hydrogen sulfite (KHS03).EPES was prepared by hydrosilylation of α,ω-hydrogen-containing silicone oil (α,ω-PHMS) with allyl polyoxyethylene polyoxypropylene epoxy ether (APEE550) using chloroplatinic acid as the catalyst. The optimum conditions of sulfonation reaction were investigated by single factor test. The chemical structure of SPES was confirmed by infrared spectroscopy (FTIR). The experimental results were showed as follows. The optimum conditions of sulfonation reaction were as follows: reaction temperature 80 ℃, reaction time 5 h, n(KHSOs) :n(EPES)=2.6:1. The FTIR analysis showed that the expected product was synthesized. Its critical micelle concentration(cmc) was determined by the surface tensiometer to be 2.Ox103 g/mL, and critical surface tension (ycm) to be 24.6 mN/m .关键词
