UREA-SILOXANE COMPOSITIONS AND METHODS OF MAKING THE SAME

摘要

An amphiphilic saccharide-urea-siloxane composition includes an amino-functional prepolymer reacted with saccharide lactone. The composition is prepared by reacting an amino-alkyl functional siloxane with isocyanate to form the amino-functional prepolymer, the molar ratio of amine in the amino-alkyl functional siloxane to cyanate in the isocyanate being greater than 1.
