Description
Summary:Hydroxyalkyl-functionalized organosilicon compounds have been prepared from hydrogen-containing organosilicon compounds by hydrosilylation. Various carboxyalkyl-modified organosilicon compounds were then prepared by reacting the hydroxyalkyl-functionalized organosilicon compounds with various cyclic acid anhydrides under solvent and catalyst free. The effects of the nature of the hydroxyalkyl functional groups and the structure of the organosilicon compounds on the ring-opening reaction have been investigated. The synthesized carboxyalkyl-modified organosilicon compounds have been used to treat cotton fabric samples, and the effects of their structures on the softness, whiteness, breaking strength, hydrophilicity, and fiber surface morphology of the cotton have been studied.
