    • A suspension and a method of preparation are provided herein. The suspension comprises a continuous aqueous phase (a), a substance (b) that is capable of transport through the aqueous phase thereby resulting in Ostwald ripening of the substance, and a dispersing agent (c). The dispersing agent comprises the reaction product of at least one monomer (i) and at least one additional monomer (ii). The at least one monomer (ii) is represented by the general formula (1) wherein R is hydrogen, an alkyl group or an aryl group, R1 is an alkyl group having at least 2 carbon atoms, k is 2 to 4, and n is at least about 10. The at least one additional monomer (ii) has unsaturated functionality and contains at least one carbonyl group. The dispersing agent is present in the suspension in an amount sufficient to limit Ostwald ripening of the substance (b) in the suspension. R2C═CR—O—R1—(OCkH2k)n—OH  (I)
    • 本文提供了悬浮液和制备方法。 悬浮液包括连续的水相(a),能够通过水相输送的物质(b),从而导致物质的Ostwald熟化,以及分散剂(c)。 分散剂包含至少一种单体(i)和至少一种另外的单体(ii)的反应产物。 所述至少一种单体(ii)由通式(1)表示,其中R是氢,烷基或芳基,R 1是具有至少2个碳原子的烷基,k是2至4,n 至少约10个。所述至少一种另外的单体(ii)具有不饱和官能团并含有至少一个羰基。 分散剂以足以限制悬浮液中物质(b)的奥斯特瓦尔德熟化的量存在于悬浮液中。 R2C = CR-O-R1-(OCkH2k)n-OH(I)
