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. En un aspecto, la invencion proporciona un metodo para hacer una combinacion polimerica de nylon 6/siliocna que comprende las etapas de preparar una emulsion polimerica silicona que comprende un polimero silicona disperso en una fase continua liquida; introducir la emulsion polimerica de silicona en una reaccion de abertura de anillo de nylon o antes de o durante el medio de reaccion de abertura de anillo de nylon o en donde el medio de reaccion comprende caprolactama; y abrir el anillo y hacer reaccionar la caprolactama, proporcionando con eso una combinacion de emulsion polimerica de nylon 6/silicona. Tambien se proporcionan combinaciones polimericas de nylon 6/silicona por la invencion en la presente.
