In a previous study, we have ascertained that the charge distribution in hydrogel microspheres (microgels) plays a crucial role in controlling the nanocomposite structure of the polystyrene obtained from the seeded emulsion polymerization (SEP) of styrene in the presence of microgels. However, all these polymerizations were conducted at high temperature, where most of these microgels were dehydrated and deswollen. In the present study, we initially verified that the nanocomposite microgels can be synthesized even when the seed microgels are swollen and hydrated during the SEP of styrene. These highly swollen microgels were used as the nucleation sites for the polystyrene, and subsequently the propagation of the hydrophobic polystyrenes proceeded within water-swollen microgels.

水溶胀水凝胶微球存在下苯乙烯的种子乳液聚合

在先前的研究中,我们已经确定了水凝胶微球(微凝胶)中的电荷分布在控制由存在微凝胶的苯乙烯的种子乳液聚合(SEP)获得的聚苯乙烯的纳米复合结构中起着至关重要的作用。然而,所有这些聚合都是在高温下进行的,其中大多数这些微凝胶都被脱水和脱溶胀。在本研究中,我们初步验证了即使在苯乙烯的SEP过程中种子微凝胶溶胀和水合时,也可以合成纳米复合微凝胶。这些高度溶胀的微凝胶被用作聚苯乙烯的成核位点,随后疏水性聚苯乙烯的扩散在水溶胀的微凝胶中进行。
