    摘要： A method of preparing polymer particles having narrow size distribution in a suspension process employing a solid colloidal stabilizing agent. The solid colloidal stabilizer is a copolymer of about 25 to about 80% by weight, based on total monomer weight, of an additional polymerizable nonionic oleophilic monomer, about 5 to about 45%, by weight, of an addition polymerizable nonionic hydrophilic monomer, about 1 to about 50% of an addition polymerizable ionic monomer, and 0 to about 20 percent, by weight, of a crosslinking monomer having at least two addition polymerizable groups. Also disclosed are polymeric particles comprising a core polymer covered by a layer of the smaller copolymer stabilizer particles and electrostatographic toners comprising such polymeric particles.

    摘要： An indicator composition can be exposed to various environmental conditions stimuli such as in sterilization or storage processes. This indicator composition has a) a first polymeric particle comprising a solid continuous polymeric phase and a first reactant, the first polymeric particle having a mode particle size equal to or less than 50 μm; and b) a second reactant outside of the first polymeric particle, which second reactant is capable of reacting with the first reactant when exposed to a chosen environmental condition stimulus. The indicator composition can be used by exposing it to the environmental condition stimulus for a sufficient time to cause a detectable change in the indicator composition such as a detectable color change.

    摘要： Porous organic polymeric films having multiple discrete cavities can be prepared by applying a water-in-oil emulsion that includes a cavity stabilizing hydrocolloid on the inner walls of the multiple discrete cavities to a substrate. The multiple discrete cavities can also include organic catalytic materials for various catalytic reactions, markers materials for security applications, or the multiple discrete cavities can be used to increase opacity, hydrophobicity, or other desirable properties compared to nonporous organic polymeric films composed of the composition and dry thickness. Water and oil from the applied water-in-oil emulsion can be removed by evaporation in a suitable process, and the applied porous organic polymeric film can be provided as a uniform material or in a patternwise fashion.

    摘要： Polymeric porous particles have a continuous 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.
