ABSTRACT:
A method is provided for making silicone-polyamides by effecting reaction between aroylhalide terminated organosiloxane and organic diamine. Optionally, organic polyacid halide can be used in combination with the aroylhalide terminated organosiloxane when reaction is effected with the organic diamine.
