wherein the molecular weight of the copolymer structure is 120,000 or less g/mole, m and t are both greater than 0, 8%≦p≦80%, y≧0, z≧0, and X is selected from —Cl, —Br and —I.

Provided are a pickering emulsion including: 0.01-20 wt % of particles having an average particle diameter of 10 nm-100 μm, and 0.01-20 wt % of a non-ionic water-soluble polymer, wherein the particles are positioned on an oil droplet surface, and a method of preparing the same.

Polymeric porous particles have a continuous organic solid phase and at least two sets of discrete pores that are isolated from each other within the continuous phase and that have different average sizes. One set of discrete pores has a larger average size than another set of discrete pores by at least 50%. At least one set of discrete pores is free of detectably different marker materials. There porous particles can be prepared using evaporative limited coalescence techniques with especially chosen discrete pore stabilizing hydrocolloids to protect the pores during formation and to provide the different average sizes. The resulting porous particles can be incorporated into articles of various types and having various shapes.
