Suspensions obtained by micellar polymerization
The present invention relates to the use of a sequential copolymer (P) comprising at least one chain (C) obtained by micellar polymerization in an aqueous medium (M) for keeping solid particles (p) suspended in an aqueous fluid (F). The chain (C) is soluble in an aqueous fluid (F) and is formed from a series of hydrophilic monomers interrupted at different points by a plurality of hydrophobic sequences (B) of substantially the same size. The chain (C) is obtained by introducing a surfactant into the aqueous medium (M) at a concentration above the critical micelle molar concentration. Each of the hydrophobic sequences comprises substantially the same defined number nH of hydrophobic monomers, wherein nH is between 12 and 30. The molecular weight of the sequence copolymer (P) is greater than 1000000 g/mol. The solid particles (p) are suspended in the aqueous fluid (F) at 180 DEG F for more than 24 hours.
本发明涉及包含至少一种通过在水性介质(M)中进行胶束聚合获得的链(C)的序列共聚物(P)用于保持固体颗粒(p)在水性流体(F)中悬浮的用途。链(C)在水性流体(F)中是可溶的，并且由在不同点处被多个大致相同尺寸的疏水序列(B)中断的一系列亲水性单体形成。链(C)通过向水性介质(M)中以高于临界胶束摩尔浓度的浓度引入表面活性剂来获得。疏水序列中的每一个包含大致相同的限定数目nH的疏水性单体，其中nH在12与30之间。序列共聚物(P)的分子量大于1000000g/mol。固体颗粒(p)在180°F下在水性流体(F)中悬浮超过24小时。
