This review article covers recent developments in thiol-X polymerizations as applied to the production of polymer colloidal particles. These polymerizations include thiol-ene, thiol-yne, thio-Michael, and thio-isocyanate polymerizations. Such thiol-X chemistries are facile reactions that offer high yields, rapid synthesis using mild conditions, orthogonality with other methods of organic synthesis, compatibility with a variety of monomer species, and can be radical or base mediated. Recent years have seen the employment of these reactions for the synthesis of polymer colloids in heterogeneous polymerizations such as suspension, dispersion, emulsion, and miniemulsion polymerizations, using microfluidic and batch production methods. A particular feature of thiol-X chemistries is their step-growth mechanism for molecular weight development, which contrasts with chain-growth polymerizations that are more commonly used in heterogeneous polymerizations. This aspect of thiol-X polymerizations allows for straightforward polymer functionalization simply through controlling the functional group stoichiometry. Another benefit is that radical-mediated thiol-X chemistries can be conducted with photo, thermal, or redox initiation, which epitomizes the practicality/adaptability of these reactions. Examples of highly functionalized thiol-X colloidal polymers are provided along with how such functionalization can be leveraged in order to provide desired properties. Therefore, polymer colloids made by thiol-X chemistries are expected to be a platform upon which many new technologies can be built.

逐步生长的Thiol-X聚合的聚合物胶体

这篇综述文章涵盖了用于聚合物胶体颗粒生产的硫醇X聚合反应的最新进展。这些聚合包括硫醇-烯,硫醇-炔,硫代-迈克尔和硫代异氰酸酯聚合。这样的硫醇-X化学反应是容易获得的反应,可提供高收率,在温和条件下快速合成,与其他有机合成方法正交,与多种单体种类相容且可通过自由基或碱介导。近年来,已经看到使用微流体和间歇生产方法在非均相聚合如悬浮,分散,乳液和细乳液聚合中使用这些反应来合成聚合物胶体。巯基X化学物的一个特殊特征是其分子量发展的逐步增长机制,这与非均相聚合中更常用的链增长聚合相反。硫醇-X聚合反应的这一方面,只需通过控制官能团的化学计量即可实现简单的聚合物官能化。另一个好处是自由基介导的硫醇X化学反应可以通过光引发,热引发或氧化还原引发进行,这体现了这些反应的实用性/适应性。提供了高度官能化的硫醇-X胶体聚合物的实例,以及如何利用这种官能化来提供所需的性能。因此,通过硫醇-X化学方法制得的聚合物胶体有望成为可以建立许多新技术的平台。硫醇-X聚合反应的这一方面,只需通过控制官能团的化学计量即可实现简单的聚合物官能化。另一个好处是自由基介导的硫醇X化学反应可以通过光引发,热引发或氧化还原引发进行,这体现了这些反应的实用性/适应性。提供了高度官能化的硫醇-X胶体聚合物的实例,以及如何利用这种官能化来提供所需的性能。因此,通过硫醇-X化学方法制得的聚合物胶体有望成为可以建立许多新技术的平台。硫醇-X聚合反应的这一方面,只需通过控制官能团的化学计量即可实现简单的聚合物官能化。另一个好处是自由基介导的硫醇X化学反应可以通过光引发,热引发或氧化还原引发进行,这体现了这些反应的实用性/适应性。提供了高度官能化的硫醇-X胶体聚合物的实例,以及如何利用这种官能化来提供所需的性能。因此,通过硫醇-X化学方法制得的聚合物胶体有望成为可以建立许多新技术的平台。另一个好处是自由基介导的硫醇X化学反应可以通过光引发,热引发或氧化还原引发进行,这体现了这些反应的实用性/适应性。提供了高度官能化的硫醇-X胶体聚合物的实例,以及如何利用这种官能化来提供所需的性能。因此,通过硫醇X化学方法制得的聚合物胶体有望成为可以建立许多新技术的平台。另一个好处是自由基介导的硫醇X化学反应可以通过光引发,热引发或氧化还原引发进行,这体现了这些反应的实用性/适应性。提供了高度官能化的硫醇-X胶体聚合物的实例,以及如何利用这种官能化来提供所需的性能。因此,通过硫醇X化学方法制得的聚合物胶体有望成为可以建立许多新技术的平台。
