Polyether modified polysiloxane was synthesized by the hydrosilation reaction of hydrogen containing silicone fluid (PHDS)and allyl polyether(APE), using chloroplatinic acid as the catalyst. On the base, the amino modified polyether-siloxane as softening for paper was prepared by the amination of ethanolamine. It was the optimized synthesis condition of the hydrosilation reaction that the ratio of PHDS and APE was 1∶8, the reaction time was 4 h, the reaction temperature was 90~120. The softness...
