溶液聚合制备微凝胶一般是在极稀溶液中进行,为突破这一限制,研究者们进行了多方面的尝试。本文主要从小分子单体溶液聚合、大分子单体溶液聚合及聚合物溶液交联三方面概括介绍了近年来溶液聚合制备微凝胶的研究状况,展望了溶液聚合制备微凝胶的研究发展前景。
Synthesizing microgels in solution is typically characterized with very low initial monomer concentration and quite incomplete conversion, which are disadvantageous to practice. In order to overcome these shortcomings, various attempts have been made in recent years. In this review, the latest investigations on the synthesis of microgels through polymerization of monomer or macromonomer in a concentrated solution, or cross-linking linear macromolecules directly in solution were overviewed and the research work need to be done in future was discussed.
