Abstract
In one aspect, the invention provides a method of making a nylon 6/silicone polymer blend comprising the steps of preparing a silicone polymer emulsion comprising a silicone polymer dispersed in a liquid continuous phase; introducing the silicone polymer emulsion into a nylon 6 ring opening reaction either prior to or during the nylon 6 ring opening reaction medium wherein the reaction medium comprises caprolactam; and opening the ring and reacting the caprolactam, thereby providing a nylon 6/silicone polymer emulsion blend. Nylon 6/silicone polymer blends are also provided by the invention herein.
