Abstract: A process including: agitating a mixture including a liquid and a plurality of resin particles within a vessel at a first shear condition; circulating a portion of the mixture from the vessel through a mixer; adding not all at once an aggregating agent for the resin particles and mixing the aggregating agent with the circulating mixture portion within the mixer at a second shear condition more intensive than the first shear condition to result in a post-mixer circulating composition; and returning the post-mixer circulating composition to the vessel wherein the post-mixer circulating composition undergoes the agitating at the first shear condition.

Abstract: A process including: heating to a first polymerization temperature a first mixture including a free radical polymerizable monomer, a free radical initiator, and a stable free radical compound to polymerize only a portion of the monomer, resulting in a prepolymer composition; shearing a second mixture including the prepolymer composition, a continuous phase liquid, and a stabilizing compound to create a miniemulsion; and flowing the miniemulsion within a polymerization reactor and heating the miniemulsion at a second polymerization temperature to form polymeric particles wherein the formation of the polymeric particles occurs while the miniemulsion flows within the reactor.

Abstract translation: 一种方法，包括：将第一种混合物加热至第一种聚合温度，该混合物包括可自由基聚合的单体，自由基引发剂和稳定的自由基化合物，仅聚合一部分单体，得到预聚物组合物; 剪切包含预聚物组合物，连续相液体和稳定化合物的第二混合物以产生细乳液; 并使细乳液在聚合反应器内流动并在第二聚合温度下加热细乳液以形成聚合物颗粒，其中在细乳液在反应器内流动时发生聚合物颗粒的形成。
