    • Silicone-polyether block copolymers are disclosed, having the average formula: R4R12Si(OR52Si)m{[R2O(CqH2qO)pR2R12Si(OR52Si)k]nR2O(CqH2qO)pR2R12Si)m}hOSiR12R4 wherein R1 is C1-C10 hydrocarbyl; R2 is C1-C10 hydrocarbylene; R3 is R1 or H; R4 is —R2—NR32 or —R2—NR3—R2—NR32; R5 is R1 or R4; h is 1 to 100; k is 2 to 500; m is 2 to 500; n is 0 to 30; p is 2 to 120; and q is 2 to 4. The silicone-polyether block copolymers comprise two terminal amine functionalities and may comprise varying degrees of pendent amine functionality. In a method for synthesizing linear silicone-polyether block copolymers of the above formula, a reaction mixture is formed by combining a polyether, an organosilicon component, an endblocking agent, and a catalyst. Thereupon, the reaction mixture is heated to produce a silicone-polyether block copolymer having at least one pendent amine functionality and a number-average molecular weight from 2000 to 500,000. Also disclosed are silicone-polyether block copolymers prepared according to the above method.
