Abstract:
A method for encapsulating a catalyst in a dispersed polymer particle comprising dissolving a Group 8 to Group 11 transition metal containing catalyst and a self-dispersing polymer in a solvent; adding water and optionally a base under particle forming conditions to form a dispersed polymer encapsulated catalyst comprising particles having a population number average diameter between 10 and 300 nanometers is provided.
