Abstract:
Silicone-polyether copolymers, adhesives and medical articles comprising same, and methods of making same. The silicone-polyether copolymer composition can include a backbone composition having a first (silicone) segment and a second (polyether) segment connected randomly via at least one of an oxamide linkage and a urea linkage. The method of making the silicone-polyether copolymer composition can include combining: a) a first (silicone) precursor; b) a second (polyether) precursor; and c) at least one of a diisocyanate and an oxalate compound.
